The Fabric of US War Powers Restraint in the 1950s

This paper will explore the topic of avoiding war by focusing on a U.S. military intervention that didn’t happen. Congress’s role in authorizing or restraining armed conflict was undermined after the undeclared Korean War, but an episode in the Eisenhower Administration, not examined by war powers scholars, suggests that constitutional restraints still endured, at least for non-covert armed conflict. During the Battle of Dien Bien Phu in Vietnam in 1954, in which Vietminh forces surrounded and ultimately captured a vulnerable French military base, French leaders pressed President Dwight D. Eisenhower to intervene militarily. Eisenhower contemplated U.S. intervention, including the use of nuclear weapons. Although the United States provided significant financial support, Eisenhower told French leaders that he would not intervene because he believed Congress would not authorize it. This episode shows the way Congress’s role could still constrain overt large-scale presidential unilateralism in the 1950s, keeping U.S. troops out of a devastating battle, even though, in other contexts, Eisenhower undermined political restraint through secrecy.
