who has to ratify a treaty made by the president
Treaty Clause Throughout U.S. history, the President has also made international "agreements" through congressional-executive agreements (CEAs) that are ratified with only a majority from both houses of Congress, or sole-executive agreements made by the President alone.[1] Though the Constitution does not expressly provide for any alternative to the Article II treaty procedure, Article I, Section 10 of the Constitution does distinguish between treaties (which states are forbidden to make) and agreements (which states may make with the consent of Congress).[3] The Supreme Court of the United States has considered congressional-executive and sole-executive agreements to be valid, and they have been common throughout American history. Thomas Jefferson explained that the Article II treaty procedure is not necessary when there is no long-term commitment:
War Powers Resolution The War Powers Resolution (also known as the War Powers Resolution of 1973 or the War Powers Act) (50 U.S.C. 1541â€“1548)[1] is a federal law intended to check the president's power to commit the United States to an armed conflict without the consent of the U.S. Congress. The Resolution was adopted in the form of a United States Congress joint resolution. It provides that the U.S. President can send U.S. Armed Forces into action abroad only by declaration of war by Congress, "statutory authorization," or in case of "a national emergency created by attack upon the United States, its territories or possessions, or its armed forces."
