The direct use of force is such a poor solution to any problem, it is generally employed only by small children and large nations.

Friedman’s aphorism contrasts mature problem-solving—persuasion, negotiation, trade-offs, and institutional rules—with the blunt instrument of coercion. By pairing “small children” with “large nations,” he suggests that resorting to force reflects a failure of imagination, patience, or legitimacy: children lash out because they lack better tools, while powerful states may use violence because they can, even when it is strategically and morally costly. The line also critiques realpolitik and militarism, implying that power can enable intellectual laziness—substituting compulsion for consent. In a libertarian frame, it underscores skepticism toward state violence and the preference for voluntary, decentralized solutions.
