Warren M. Christopher, a highly respected attorney, former Secretary of State and former chair of the Stanford Board of Trustees died on March 18, 2011, at the age of 85.

A graduate of the University of Southern California, Warren Christopher attended Stanford Law School, where he was president of the Law Review and was a member of the Order of the Coif.

Upon graduation, Mr. Christopher joined the Los Angeles law firm of O'Melveny& Myers LLP. He would blend a highly regarded and very distinguished law career with an equally distinguished record of public service to several American presidents.

From 1997 to 1982, Mr. Christopher served President Jimmy Carter as Deputy Secretary of State of the United States. President Carter awarded him the Medal of Freedom, the nation's highest civilian award, in January of 1981 for his role in negotiating the release of 52 Americans hostages in Iran. Mr. Christopher then rejoined O'Melveny & Myers in 1981, serving as chairman of the firm until 1992.

In 1991, Mr. Christopher was Chairman of the Independent Commission of the Los Angeles Police Department, which proposed significant reforms in the aftermath of the Rodney King incident. Mr. Christopher headed the search for a running mate for both Governor Clinton's and Vice President Gore's presidential campaigns and served as Director of the Presidential Transition Process for President Clinton.

Mr. Christopher was called on by President Clinton to serve as Secretary of State. He was sworn in as the 63rd Secretary in January of 1993 and served until January 1997. As Secretary of State, he helped bring peace to Bosnia and to parts of the Middle East. He rejoined his firm, O'Melveny & Myers, as its senior partner in 1997.

Mr. Christopher's activities have included service as President of the Board of Trustees of Stanford and as Chairman of the Board of Trustees of Carnegie Corporation of New York. He has been a Director and Vice Chairman of the Board of the Council on Foreign Relations. He was also a co-chair, with James Baker, of the National War Powers Commission, convened to determine the respective roles of the president and the congress in taking the nation to war.

He authored four books: In the Stream of History: Shaping Foreign Policy for a New Era (Stanford, 1998), Chances of a Lifetime (Scriber 2001), Diplomacy, the Neglected Imperative (published privately in 1981) and Random Harvest (published privately in 2005).

"Warren Christopher was a distinguished attorney, an outstanding diplomat, an astute statesman and a wonderful person,"In 2008, O'Melveny & Myers and a number of its current and retired partners committed $1.5 million to endow the Warren Christopher Professorship of the Practice of International Law and Diplomacy, a joint appointment between Stanford Law School and the Freeman Spogli Institute for International Studies.

"Warren Christopher was a unique and a very special person," said Law School Dean Larry Kramer. "He was brilliant and thoughtful, generous, modest, and unselfish to the core. In everything he said and did, he embodied what we mean when we talk of someone as classy.

 "Warren Christopher was a distinguished attorney, an outstanding diplomat, an astute statesman and a wonderful person," said Coit D. Blacker, Director of the Freeman Spogli Institute for International Studies and the Olivier Nomellini Professor in International Studies. "How appropriate it is to have a gift that lives on for the next generation of leaders and public servants that honors his talent, his prescience, his leadership and his remarkable career in both the law and diplomacy. We will miss him and his wise counsel."

Each president of the United States enters office thinking he will be able to define the agenda and set the course of America's relations with the rest of the world. And, almost invariably, each confronts crises that are thrust upon him-wars, revolutions, genocides, and deadly confrontations. Neither Woodrow Wilson nor FDR imagined having to plunge America into world war. Truman had to act quickly, and with little preparation, to confront the menace of Soviet expansion at war's end. JFK, for all his readiness to "bear any burden" in the struggle for freedom, did not expect his struggle to contain Soviet imperial ambitions would come so close to the brink of nuclear annihilation. Nixon was tested by a surprise war in the Middle East. Carter's presidency was consumed by the Shah's unraveling and the Iranian revolution. George H.W. Bush rose to the challenge of communism's collapse and Saddam Hussein's invasion of Kuwait. Clinton squandered the opportunity to stop a genocide in Rwanda and waited tragically too long before stopping one in Bosnia. George W. Bush mobilized the country to strike back after September 11, but, in the view of many, he put most of his chips in the wrong war.

In the eye of the historical storm, and in the absence of a challenge as immediate and overpowering as September 11, Pearl Harbor, or the Nazis' march across Europe, it is risky to identify any set of world events as game-changing. Yet that is what many analysts, including myself, believe the Arab revolutions of 2011 are. And a surprising number of specialists-including hard-eyed realists like Fareed Zakaria-have seized upon the crisis in Libya as a defining moment not just for the United States in the region but for the foreign policy presidency of Barack Obama as well.

To date, one could say that Obama has had a surprisingly good run for a foreign policy neophyte. He has revived the momentum for arms control with a new START treaty with Russia, while pressing the issue of human rights within Russia. He has managed the meteoric rise of China decently, while improving relations with India. He has not cut and run from Iraq-as most Republicans were convinced he would. And he has ramped up but at least set limits to our involvement in Afghanistan. As the Arab revolutions have gathered momentum, he has increasingly positioned the United States on the side of democratic change. His statements and actions have not gone as far as democracy promotion advocates (like myself) would have preferred, but they have overridden cautionary warnings of the foreign policy establishment in the State Department, the Pentagon, think tanks, and so on. Without Obama's artful choreography of public statements and private messages and pressures, Hosni Mubarak might still be in power today.

All of this, however, may appear in time only a prelude to the fateful choice that Obama will soon have to make-and, one fears, is already making by default in a tragically wrong way-in Libya. Why is Libya-with its six million people and its significant but still modest share of global oil exports-so important? Why must the fight against Muammar Qaddafi-a crazy and vicious dictator, but by now, in his capacity for global mischief, a largely defanged one-be our fight?

When presidents are tested by crisis, the world draws their measure, and the impressions formed can have big consequences down the road. After watching Jimmy Carter's weak and vacillating posture on Iran, the Soviets figured he'd sit on the sidelines if they invaded and swallowed Afghanistan. They misjudged, but Afghanistan and the world are still paying the price for that misperception. In the face of mixed messages and a long, cynical game of balance-of-power, Saddam too, misjudged that he could get away with swallowing up Kuwait in 1991. When the United States did not prepare for war as naked aggression swept across Asia and Europe, the Japanese thought a quick strike could disable and knock out the slumbering American giant across the Pacific. When Slobodan Milosevic and his Bosnian Serb allies launched their war of "ethnic cleansing," while "the West"-which is always to say, first and foremost, the United States-wrung its hands, many tens of thousands of innocent people were murdered and raped before President Bill Clinton finally found the resolve to mix air power and diplomacy to bring the genocidal violence to a halt.

If Muammar Qaddafi succeeds in crushing the Libyan revolt, as he is well on his way to doing, the U.S. foreign policy establishment will heave a sad sigh of regret and say, in essence, "That's the nasty business of world politics." In other words: nasty, but not our business. And so: not their blood on our hands. But, when we have encouraged them to stand up for their freedom, and when they have asked for our very limited help, it becomes our business. On February 23, President Obama said: "The United States ... strongly supports the universal rights of the Libyan people. That includes the rights of peaceful assembly, free speech, and the ability of the Libyan people to determine their own destiny. These are human rights. They are not negotiable. ... And they cannot be denied through violence or suppression." Yet denying them through murderous violence and merciless suppression-with a massacre of semi-genocidal proportions likely waiting as the end game in Benghazi-is exactly what Qaddafi is in the process of doing.

Barack Obama has bluntly declared that Qaddafi must go. The Libyan resistance, based in Benghazi, has appealed urgently for the imposition of a no-fly zone. Incredibly, the Arab League has endorsed the call, as has the Gulf Cooperation Council. France has recognized the rebel provisional government based in Benghazi as Libya's legitimate government-while Obama studies this all. Can anyone remember a time when France and the Arab League were ahead of the United States on a question of defending freedom fighters?

There is much more that can be done beyond imposing a no-fly zone. No one in their right mind is calling for putting American boots on the ground in Libya. But we can jam Qaddafi's communications. We can, and urgently should, get humanitarian supplies and communications equipment, including satellite modems for connection to the Internet, to the rebels in Benghazi, where they can be supplied by sea. And we should find a way to get them arms as well. Benghazi is not a minor desert town. It is Libya's second largest city, a major industrial and commercial hub, and a significant port. Through it, a revolt can be supplied. If Benghazi falls to Qaddafi, it will fall hard and bloodily, and the thud will be heard throughout the world.

Time may be running out. As the Los Angeles Times reported yesterday, "All that stands between Kadafi and rebel headquarters in Benghazi are disorganized volunteers and army defectors spread thinly along the coastal highway." They have passion and courage, but they lack weaponry, strategy, and training. Like so many rebel movements, they need time to pull these all together. Time is what a no-fly zone and an emergency supply line can buy them.

Libya's rebels are pleading for our help. "Where is America?" asked one of them, quoted in the L.A. Times, who was manning a checkpoint in Port Brega. "All they do is talk, talk, talk. They need to get rid of these planes killing Libyan people." The "they" he was referring to was the Americans, beginning with their leader-one would hope, still the leader of the "free world"-President Obama.

Many prudent reasons have been offered for doing nothing. It is not our fight. They might lose anyway. We don't know who these rebels really are. We have too many other commitments. And so on. The cautions sound reasonable, except that we have heard them all before. Think Mostar and Srebrenica. And we had a lot of commitments in World War II as well, when we could have and should have bombed the industrial infrastructure of the Holocaust. As for the possibility that the rebels might lose-a prospect that is a possibility if we aid them and a near certainty if we do not-which would be the greater ignominy: To have given Libya's rebels the support they asked for while they failed, or to have stood by and done absolutely nothing except talk while they were mowed down in the face of meek American protests that the Qaddafi's violence is "unacceptable"?

Oh yes. There is also the danger that China will veto a U.N. Security Council Resolution calling for a no-fly zone. Part of us should hope they do. Let the rising superpower-more cynical than the reigning one ever was-feel the first hot flash of hatred by Arabs feeling betrayed. Go ahead, make our day.

Presidents do not get elected to make easy decisions, and they certainly never become great doing so. They do not get credit just because they go along with what the diplomatic and military establishments tell them are the "wise and prudent" thing to do. This is not Hungary in 1956. There is no one standing behind Qaddafi-not the Soviet Union then, not the Arab League now, not even the entirety of his own army. That is why he must recruit mercenaries to save him. Qaddafi is the kind of neighborhood bully that Slobodan Milosevic was. And he must be met by the same kind of principled power. For America to do less than that now-less than the minimum that the Libyan rebels and the Arab neighbors are requesting-would be to shrink into global vacillation and ultimately irrelevance. If Barack Obama cannot face down a modest thug who is hated by most of his own people and by every neighboring government, who can he confront anywhere?

For the United States-and for Barack Obama-there is much more at stake in Libya than the fate of one more Arab state, or even the entire region. And the clock is ticking.
