Despite its attempt to soften criticism of the war, there is no evidence the Bush administration is capable of self-correction.

That came home to me the other day while listening to a senior administration official deliver an off-the-record tour d'horizon of American foreign policy. He is among the best minds in this administration, counted among the ranks of the realists, rather than the neoconservatives.

The United States stands alone as the most powerful nation in the world, the official began. In no previous moment of human history has a single state enjoyed such a dominant position.

When it comes to managing its relations with other would-be powers -- Europe, China, Japan and India -- the United States has done "extraordinarily well,'' he said.

The tensions generated by the war in Iraq have eased, the senior foreign policy official confidently asserted. The Europeans are content to gaze intently inward, he observed, while America strides the globe.

Japan is embracing the United States in a very close relationship that shows no sign of unraveling. Meanwhile the Bush administration has forged a growing partnership with India.

When it comes to China, the administration has chosen the path of accommodation and integration rather than containment of the rising power. He expressed confidence that American power and the prospect of democracy in China will secure the peace.

The only remaining challenge for the United States is to combat the threat of a radical Islamist movement that seeks to acquire weapons of mass destruction. For that, there is the promotion of democracy and American values around the world. After all, the official said with not even a nod to humility, "the U.S. is the most successful country that has ever existed.''

A year or two ago, the American people embraced this vision of a confident colossus, a Gulliver among the Lilliputians. That was before they watched the giant tied down in its attempt to export those American values by force of arms in Iraq.

The arrogance of this administration would be barely tolerable if it were not paired with a stunning incompetence, on display from Kabul to Katrina. That deadly combination has weakened American strength in the world. It has emboldened far more serious challengers in Iran and North Korea, who see the United States as too bogged down in Iraq to credibly threaten them with the use of force.

The war rated barely a mention in the sweeping view offered by the senior administration official, except indirectly. He offered a realist defense of the administration's democracy crusade.

World War II was fought with democratic goals, the official pointed out. And the Cold War -- the model for the current struggle against Islamic extremism -- was not just about balancing the power of the Soviet Union. The wars in Korea and Vietnam were really about determining which system those countries chose, he argued.

Those are curious examples to cite as a defense of the decision to go to war in Iraq. The United States shored up authoritarian regimes in Korea and Vietnam to counter the communist threat. Vietnam was a strategic mistake that took decades to overcome. And democracy came to Korea more than 35 years later, after a long period of economic development.

President Bush cited the democratic transformation of Korea -- along with Taiwan and Japan -- in a recent speech during his trip to Asia. But these are examples of the "conventional story in which you become rich and then you become democrats,'' as the senior official put it so well.

The administration proposes however to skip this long, but necessary, path to democratic capitalism when it comes to the Middle East. The policies of security and stability have failed there and a quicker route to democratic change is called for. But there is no historical evidence to suggest that this is any more than another manifestation of a blind belief in American power.

Democratic values have always been essential to American foreign policy. In practice, however, American administrations have often made painful choices between stability and the promotion of democracy. We saw that too often during the Cold War -- in Budapest in 1956, Prague in 1968 or Tibet in 1959.

The administration might do well to recall the words of candidate Bush, uttered Oct. 11, 2000.

"It really depends on how our nation conducts itself in foreign policy. If we're an arrogant nation they'll resent us,'' Bush said. "But if we are a humble nation, they'll respect us.''

In the old popular song about the rout by Americans at New Orleans during the War of 1812, the British "ran so fast the hounds couldn't catch 'em." Even allowing for patriotic hyperbole, it can hardly be argued that the British extricated themselves with a great deal of dignity, particularly given that another battle in the same war inspired the American national anthem.

The impact of that defeat on the British national psyche is now obscure, but nearly two centuries later, as the Americans and their British allies seek to extricate themselves from Iraq, the story of how a superpower looks for a dignified way out of a messy and often unpopular foreign conflict has become a historical genre of sorts. As the pressure to leave Iraq increases, that genre is receiving new and urgent attention.

And in the shadow of the bleak and often horrific news emerging from Iraq nearly every day, historians and political experts are finding at least a wan hope in those imperfect historical analogies. Even in the absence of a sudden and dramatic shift on the battlefield toward a definitive victory, there may still be a slight opening, as narrow as the eye of a needle, for the United States to slip through and leave Iraq in the near future in a way that will not be remembered as a national embarrassment.

Most of the recent parallels do not seem to offer much encouragement for a confounded superpower that wants to save face as it cuts its losses and returns home. Among them are the wrenching French pullout from Algeria, the ill-fated French and American adventures in Vietnam, the Soviet humiliation in Afghanistan and the disastrous American interventions in Beirut and Somalia.

Still, there are a few stories of inconclusive wars that left the United States in a more dignified position, including the continuing American presence in South Korea and the NATO peacekeeping mission in Bosnia. But even those stand in stark contrast to the happier legacy of total victory during World War II.

The highly qualified optimism of these experts about what may still happen in Iraq - let's call it something just this side of hopelessness - has been born of many factors, including greatly reduced expectations of what might constitute not-defeat there. The United States already appears willing to settle - as if it were in a relationship that had gone sour but cannot quite be resolved by a walk out the door, punctuated with a satisfying slam.

Alongside the dampening of hopes, there has also been a fair amount of historical revisionism regarding the darker tales of conflicts past: a considered sense that if the superpowers had made different decisions, things could have turned out more palatably, and that they still might in Iraq.

Maybe not surprisingly, Vietnam is the focus of some of the most interesting revisionism, including some of it immediately relevant to Iraq, where the intensive effort to train Iraqi security forces to defend their own country closely mirrors the "Vietnamization" program in South Vietnam. If Congress had not voted to kill the financing for South Vietnam and its armed forces in 1975, argues Melvin R. Laird in a heavily read article in the current issue of Foreign Affairs, Saigon might never have fallen.

"Congress snatched defeat from the jaws of victory by cutting off funding for our ally in 1975," wrote Mr. Laird, who was President Nixon's defense secretary from 1969 to 1973, when the United States pulled its hundreds of thousands of troops out of Vietnam.

In an interview, Mr. Laird conceded that the American departure from Vietnam was not a pretty sight. "Hell, the pictures of them getting in those helicopters were not good pictures," he said, referring to the chaotic evacuation of the American embassy two years after Vietnamization was complete, and a year after Nixon resigned. But on the basis of his what-if about Vietnam, Mr. Laird does not believe that all is lost in Iraq.

"There is a dignified way out, and I think that's the Iraqization of the forces over there," Mr. Laird said, "and I think we're on the right track on that."

Many analysts have disputed the core of that contention, saying that large swaths of the Iraqi security forces are so inept they may never be capable of defending their country against the insurgents without the American military backing them up. But Mr. Laird is not alone in his revisionist take and its potential application to Iraq.

William Stueck, a history professor at the University of Georgia who has written several books on Korea, calls himself a liberal but says he buys Mr. Laird's basic analysis of what went wrong with Vietnamization.

Korea reveals how easy it is to dismiss the effectiveness of local security forces prematurely, Mr. Stueck said. In 1951, Gen. Matthew Ridgeway felt deep frustration when Chinese offensives broke through parts of the line defended by poorly led South Korean troops.

But by the summer of 1952, with intensive training, the South Koreans were fighting more effectively, Mr. Stueck said. "Now, they needed backup" by Americans, he said. By 1972, he said, South Korean troops were responsible for 70 percent of the front line.

Of course, there are enormous differences between Iraq and Korea. Korean society was not riven by troublesome factions, as Iraq's is, and the United States was defending an existing government rather than trying to create one from scratch.

Another intriguing if imperfect lesson can be found in Algeria, said Matthew Connelly, a Columbia University historian. There, by March 1962, the French had pulled out after 130 years of occupation.

That long colonial occupation, and the million European settlers who lived there before the bloody exodus, are major differences with Iraq, Mr. Connelly noted. But there were also striking parallels: the insurgency, which styled its cause as an international jihad, broke down in civil war once the French pulled out; the French, for their part, said theirs was a fight to protect Western civilization against radical Islam.

Like President Bush in Iraq, President Charles de Gaulle probably thought he could settle Algeria in his favor by military means, Dr. Connelly said. In the short run, that turned out to be a grave miscalculation, as the occupation crumbled under the insurgency's viciousness.

Over the long run, though, history treated de Gaulle kindly for reversing course and agreeing to withdraw, Mr. Connelly said. "De Gaulle loses the war but he wins in the realm of history: he gave Algeria its independence," he said. "How you frame defeat, that can sometimes give you a victory."

The Americans in Beirut and the Soviets in Afghanistan are seen, even in the long view, as cases of superpowers paying the price of blundering into a political and social morass they did not understand.

For the Soviets, that mistake was compounded when America outfitted Afghan rebels with Stinger missiles capable of taking down helicopters, nullifying a key Soviet military superiority. "I don't think they had a fig leaf of any kind," said Henry Rowen, a fellow at the Institute for International Studies at Stanford who was assistant secretary of defense for international security affairs from 1989 to 1991. "They just left."

In Beirut, the Americans entered to protect what they considered a legitimate Christian-led government and ended up, much as in Iraq, in the middle of a multipronged civil conflict. In October 1983, a suicide attack killed 241 American servicemen at a Marines barracks, and four months after that, with Muslim militias advancing, President Ronald Reagan ordered the remaining marines withdrawn to ships off the coast, simply saying their mission had changed. The episode has been cited by Vice President Dick Cheney as an example of a withdrawal that encouraged Arab militants to think the United States is weak.

Today, even as expectations for Iraq keep slipping, some measure of victory can still be declared even in a less-than-perfect outcome, said Richard Betts, director of the Saltzman Institute of War and Peace Studies at Columbia. For example, he said, an Iraqi government that is authoritarian but not totalitarian might have to do.

The key point, he said, is that under those circumstances, the outcome "doesn't look like a disaster even if it doesn't look good."

We hardly needed the 30th anniversary of the Vietnam War's end to remind us of that war. Iraq provides daily reminders, prompting frequent comparisons to Vietnam. While many of the analogies are misplaced, looking back at America's intervention in Vietnam can be valuable.

The major challenge now facing the United States in Iraq is to establish a stable and powerful indigenous military to provide a secure environment for nation-building.

The U.S. Army's initial unwillingness to integrate South Vietnamese soldiers into its military plans--and its later inability to motivate the indigenous troops to take over the fighting--tells us what to avoid in Iraq.

The old Iraqi army fell apart in April 2003 as American soldiers marched on Baghdad. As the insurgency grew and American casualties mounted, the coalition forces started putting Iraq's army together again. Many of the same soldiers came back to sign up--it was only at the higher levels that Baathist officers were purged. Both Iraq and the United States have an interest in strengthening a purely Iraqi force.

Still some lessons

President Bush calls the comparison of Iraq with Vietnam a "false analogy" and accuses those who use it of sending the wrong message to the enemy and to the troops. Likewise, Rep. Richard Baker, R-La., calls the analogy "wrong, disturbing and dangerous."

In fact, Vietnam does not make for a good comparison with Iraq--but the differences are informative. The most striking difference between the two situations is in the sequence of war and nation-building. In Vietnam, the United States attempted nation-building under South Vietnamese President Ngo Dinh Diem's administration for nearly a decade before intervening directly with ground troops; in Iraq, a short and overwhelming display of force preceded nation-building. Moreover, the Americans were facing a much stronger adversary--including an organized army--in Vietnam.

Beginning in 1969, the Nixon administration implemented its policy of "Vietnamization," withdrawing U.S. troops while simultaneously turning over to the Army of the Republic of Vietnam the fighting and the pacification efforts. By 1973, the South Vietnamese army was the strongest in Southeast Asia, boasting more than 1 million soldiers and toting the most advanced weaponry, thanks to U.S. Army programs such as Enhance and Enhance Plus. However, unimpressive performances during a joint incursion into Cambodia and the 1972 spring offensive testified otherwise. Finally, on April 30, 1975, Saigon fell to the communists. Where did Vietnamization go wrong?

From the entry of American ground forces in 1965, South Vietnamese forces were made to feel marginalized in defending South Vietnam. This was mainly due to the U.S. Army's belief in 1965-69 that the South Vietnamese troops were essentially irrelevant to victory or defeat. Not only were the soldiers equipped with inferior weapons, underpaid and given poor housing compared to their American counterparts, but they also were relegated to so-called pacification missions.

U.S. soldiers had more respect for their enemies from the North than for their allies in the South. Training and communication were beset with linguistic, social and cultural barriers. By the time South Vietnamese soldiers started replacing U.S. soldiers in 1969, it was too late to induce them to adopt what had come to be regarded as U.S. strategic goals, rather than South Vietnamese ones.

It's not too late

Now, in Iraq, a window of opportunity is still open for Americans. According to Anthony Cordesman of the Center for Strategic and International Studies, the United States wasted the whole first year after the invasion in halfhearted attempts to create effective Iraqi military and police forces. The bulk of the army is made up of soldiers who were fighting Americans a few months ago. Ethnic and religious divisions among the men, and their legacy of service under an autocrat, make it difficult for them to attain modern professional military standards. However, the Iraqi people are much less distrustful of the Iraqi army than they are of occupying U.S. forces.

The Multinational Security Transition Command, set up late last year, must focus on the Iraqi army's esprit de corps. It is not too late to incorporate and integrate Iraqi forces in strategic planning and operations so that they have a stake in securing a stable Iraq. Otherwise, the Iraqi army will soon be overwhelmed by the size and hostility of a growing insurgency.

The Vietnam analogy has too often been deployed in times of political conflict in the United States. But the comparison can be useful. If we learn the right lessons from the mistakes in Vietnam, we need not be condemned to repeat them in Iraq.

Not long ago, an experimental malaria vaccine made newspaper headlines. Over six months, it more than halved serious episodes of malaria in 2,000 children in rural Mozambique. The only trouble is that it will take at least 10 years to come to market.

Fortunately, there are new, effective drugs already available that could start to loosen malaria's stranglehold on many impoverished countries. With a modest global investment, these drugs could be mobilised today.

Malaria is one of the world's greatest threats to life and human performance. Each year, it kills more than 1m people, mainly children in sub-Saharan Africa, and triggers some 500m debilitating attacks in people of all ages throughout the tropics. The toll in lost productivity is a big contributor to Africa's poor economic performance.

All concerned with malaria know that new drugs are needed. After the second world war, a drug called chloroquine became standard. Until about 20 years ago, it worked well in Africa. In addition, it was cheap, averaging 10 cents per treatment. However, chloroquine-resistant strains, which first emerged in south-east Asia, are now rife throughout Africa. The death toll from malaria is rising once again.

What makes this situation more distressing is the existence of an effective alternative. When the first signs of drug-resistant malaria appeared in Asia during the Vietnam war, Chinese scientists developed a family of drugs from sweet wormwood, a common shrub that had been used for centuries in traditional medicine. These "artemisinin compounds" are now standard components of malaria treatment in Asia, where they have proved to be the best ever anti-malarial drugs. To circumvent future drug resistance, however, the time has come to partner artemisinins with other anti-malarial drugs, creating artemisinin combination therapies (ACTs) - the same strategy that underlies the treatment of HIV and tuberculosis. In 2002, the World Health Organisation went on record urging governments to adopt such therapies rapidly in order to provide more effective malaria treatment and slow the spread of drug resistance.

Now the only remaining obstacles to these treatments in Africa are economic. At present, ACTs cost about $2 a treatment, not 10 cents. Subsidies are needed - probably in the region of $500m a year, a small amount on any global scale. The other challenge is how this money enters the drug supply chain.

To overcome the need for a new system of delivery, a recent report from the Institute of Medicine, the US-based health advisory organisation, recommended that ACTs be bought at competitive prices by an international organisation such as Unicef, then resold at a deep discount to governments and private wholesalers in countries where malaria is endemic. The main condition underlying access to subsidised ACTs would be that they flow freely through public and private channels - just as chloroquine does now. This approach would accomplish two objectives: it would allow the existing private market to support the switch to ACTs and it would keep the treatment's cost to consumers down to about the price of chloroquine.

Centralised purchasing has other advantages. It would assure a market for producers, and in particular would encourage the planting of sweet wormwood to overcome the existing reported shortage of artemisinin. It would also facilitate quality control. Moreover, the scale of any international subsidy of combination therapy would discourage the distribution of any solo drug whose use might encourage new resistance down the line.

Above all, in the case of anti-malarial drugs, centralised purchasing would provide the impetus for a swift change in the way the world treats malaria. Without a co-ordinated programme, the change is far more likely to be gradual and incomplete, the scenario most likely to jeopardise the effectiveness of artemisinins over the next few years.

There can be no excuse for delay. Resistance is overwhelming the usefulness of existing drugs, and deaths due to drug-resistant malaria are accelerating daily, especially among the poor of Africa. The IOM has proposed a feasible plan to introduce ACTs quickly. All that remains is for the international donor and finance communities to embrace the logic, allocate funds and take action once and for all against malaria.

The Presidential election campaign is in the home stretch. Neither the President nor Senator Kerry has secured a decisive advantage.

Iraq is now the central issue of debate, as one would expect, since the war is going badly, and the economy is reasonably robust. The debate is finally beginning to focus on substantive differences between the candidates after a summer in which they mainly exchanged personal attacks on their respective Vietnam records. Their strategies are now clear: Bush will challenge Kerry's steadiness and consistency; Kerry will challenge the necessity of the campaign in Iraq and the competence of the administration's efforts there. But while their diagnoses of the situation differ, their proposals for dealing with what is clearly a mess are not so clearly differentiated. Both propose to seek additional help from members of the international community; both emphasize the need to train and arm Iraqi security forces; and both are hopeful that elections will enhance the legitimacy of Iraqi leaders, fortify their efforts to dry up the insurgency, and allow American forces to be reduced and eventually withdrawn.

Historically, wars have been unkind to presidents on whose watch they occurred. The Korean War reduced Harry Truman's popularity so dramatically by 1952 that he gave up his quest for a second full term. The Vietnam War drove Lyndon Johnson from office, despite impressive domestic achievements. Victory in the Gulf War of 1991 sent George H.W. Bush's approval ratings soaring, but within a year he was defeated by an obscure Arkansas governor.

Yet President Bush still clings to a narrow lead in the polls. Why?

Senator Kerry has argued that the Iraqi campaign is a "war of choice." Perhaps so. But Osama bin Laden issued a fatwa declaring war on the United States nearly a decade ago. Whatever the outcome in Iraq, war with Islamic extremists will continue. And American voters remain nearly evenly divided as to whether John Kerry has the steadfast character and consistent judgment they want in a wartime leader.

Uneasiness about the financial and human costs of the war is growing. Casualty figures in Iraq are high compared to the numbers killed or wounded in post-cold war American interventions in Somalia, Haiti, Bosnia, and Kosovo. Yet, those earlier conflicts involved humanitarian interventions in which Americans perceived little strategic stake. However, military personnel killed in Iraq - now more than 1000 - still number less than a third of the civilians who perished in New York and Washington on 9/11. And ours is a volunteer military that is highly motivated.

When confronted by an attack, Americans have consistently taken the fight to the enemy, engaging them in combat as far from our shores as possible. The president has portrayed the campaign in Iraq as an integral feature of the war on terrorism. To at least a number of voters, the absence of any terrorist attacks in the United States since 9/11 provides evidence that his approach, while not without significant costs, is working.

Victory at the polls may be a dubious prize. Whoever is sworn in on January 20, 2005 will face daunting choices. American options in Iraq range from the "potentially disastrous" to the "extremely distasteful." We cannot simply walk away. And a host of other dilemmas - e.g. nuclear crises in Iran and North Korea, a Middle East peace process that has gotten off track, strains in the trans-Atlantic relations, a multilateral trade round that has lost momentum - demand urgent attention. Beyond this, the next president will be hampered by a gigantic fiscal deficit and a military that is stretched thin. In short, he will have few easy choices. It makes one wonder why politicians yearn for this job.
