According to the U.S. Constitution, only Congress has the power to declare war. Modern U.S. Presidents keep forgetting to seek consent of Congress. It’s only war. It’s only our Constitution.
How long has it been since we followed the clear dictate of our own Constitution?
The last time the United States formally declared war, using specific terminology, on any nation was in 1942, when war was declared against Axis-allied Hungary, Bulgaria, and Romania, because President Franklin Roosevelt thought it was improper to engage in hostilities against a country without a formal declaration of war. Since then, every American president has used military force without a declaration of war.
