"Mankind will never win lasting peace so long as men use their full resources only in tasks of war. While we are yet at peace, let us mobilize the potentialities, particularly the moral and spiritual potentialities, which we usually reserve for war"
About this Quote
The intent is both admonition and strategy. Dulles isn’t offering a soft plea for harmony; he’s arguing that “lasting peace” requires the same total commitment states routinely justify only when bullets are flying. The key phrase is “full resources.” It implies an indictment of modern politics: governments can centralize money, attention, sacrifice, and even ethical language on command, but only for violence. In that sense, war functions as society’s most effective organizer - and Dulles wants to steal its efficiency without its destruction.
The subtext has a Cold War edge. As Eisenhower’s secretary of state, Dulles championed hard containment and the moralized rhetoric of freedom versus tyranny. This quote reveals the other half of that posture: a belief that the West needed not just weapons, but conviction, unity, and purpose sturdy enough to outlast crisis cycles. “Moral and spiritual potentialities” is doing political work: it’s a call for civic seriousness and shared sacrifice, but also a way to sanctify foreign policy aims.
What makes it land is its uncomfortable mirror. If war is the only time we become fully ourselves, peace becomes a kind of moral failure. Dulles dares the listener to feel that embarrassment - and to act on it.
