Congress, the Constitution and War: The Limits on Presidential Power

There is little question that Congress could use its power of the purse to end a war. But cutting off financing is a drastic step, and one that members of Congress are understandably reluctant to take, because it can look like a refusal to support the troops. The Constitution's text, Supreme Court cases and history show, however, that Congress can instead pass laws that set the terms of military engagement. Whether it would be wise for Congress to adopt such limits is debatable; whether it has the authority to do so should not be.
