how would the war powers act have impacted president truman's initial ability to deploy us soldiers into the korean war?

The War Powers Act would have made the deployment impossible or at least questionable.

The War Powers Act of 1973 is a federal law intended to limit the U. S. President's ability to initiate or escalate military actions abroad. The President can send U. S. Armed Forces into action abroad only if Congress authorizes such action and specifies its length.

The goal of this act was to avoid another controversial conflict such as the Korean or Vietnam War.

President Truman ordered U. S. naval and air forces to fight in the Korean War in 1950. With The War Powers Act, he would not have been able to make such decision on his own, he would have had to ask for approval of such deployment in Congress first. The U. S. Congress may have had denied him his proposal and prohibited any involvement in the war if it found it unnecessary.
