The No Invading Allies Act (H.R.1936) is a 2025 bill aimed at restricting U.S. military action against three specific allied or friendly regions: Canada, Panama, and Greenland. It prohibits the use of funds for invading or seizing their territories unless war is declared, Congress authorizes it, or there is an imminent national emergency. The bill reinforces the United States’ commitment to a rules-based international order, affirms respect for partnerships, and reasserts congressional war powers. It also clearly defines the conditions under which U.S. troops may be introduced into hostilities.
