President Donald Trump ascended to office with an estimated $3.5 billion of personal wealth tied up in his global real estate empire. This has raised a variety of concerns about conflicts of interest, particularly the potential for cronyism and corruption. But the greatest danger is that U.S. foreign policy will be fundamentally distorted by the president’s business interests. We face what might be dubbed a “nepotist peace”: The United States will avoid any conflict that puts a Trump Tower, the embodiment of his familial business empire, at risk.
