Foreign Policy article calls Iran war a bigger defeat than Vietnam The United States' war against Iran represents a more serious strategic setback than the Vietnam War, contending that it directly damaged core US interests and weakened Washington's position on the global stage, a Foreign Policy analyst has reported. Writing in Foreign Policy, Paul Musgrave, an associate professor of political science at Georgetown University in Qatar, said the consequences of the conflict could prove more significant than those of Vietnam, which did not prevent the United States from ultimately prevailing in the Cold War. Musgrave described the conflict as a "war of choice" initiated by President Donald Trump and argued that it ended in a political and military disaster.
