How was the blank check problem solved after the Vietnam war?

The blank check problem, which refers to the open-ended commitment of U.S. resources and military involvement in Vietnam, was addressed through a shift in U.S. foreign policy towards more constrained military engagements. Following the war, the War Powers Act of 1973 was enacted, requiring congressional approval for military actions. This legislation aimed to limit executive power and ensure that large-scale military commitments would have legislative oversight, thereby preventing unchecked military spending and involvement in future conflicts. Additionally, the end of the draft and the establishment of an all-volunteer military further reduced the potential for similar dynamics.
