"You can always amend a big plan, but you can never expand a little one. I don't believe in little plans. I believe in plans big enough to meet a situation which we can't possibly foresee now"
About this Quote
The subtext is pure postwar executive thinking. Truman governed in an era when “a situation which we can’t possibly foresee now” wasn’t abstract humility; it was a lived condition shaped by the atomic age, the early Cold War, mass demobilization, and the new responsibilities of global leadership. Big plans are a way of building institutional shock absorbers: if the world swerves, you can recalibrate without starting from zero. That premise underwrites everything from the Marshall Plan to the architecture of containment - commitments designed to be adjusted, not abandoned.
There’s also a political tell here. By framing ambition as the only realistic option, Truman flips the usual accusation: the truly naive actors are the incrementalists who think tomorrow will resemble today. It’s a presidency asserting that consequence demands capacity, and that capacity requires daring first drafts.
