Yesterday, in response to a question about Trump's proposal to seize Iraqi oil as spoils of war, Rudy Giuliani told ABC's George Stephanopoulos: "Of course it's legal. It's a war," (laughing) "Until the war is over, anything's legal."
Um... no. Whether or not natural resources can ever be seized, the Supremacy Clause of the U.S. Constitution makes treaties the law of land. The United States is party to numerous treaties that govern conduct during wars. Moreover, we are not at war with Iraq. While our relationship with the Iraqi government isn't our best international relationship, Iraq is an ally, and the oil in Iraq legally belongs to the nation of Iraq.
