Kennedy distinguishes between the use of power for its own sake and the use of power in defence of principles. By contrasting the ‘victory of might’ with the ‘vindication of right’, he argues that the purpose of American policy during the Cuban Missile Crisis was not simply to overpower an adversary, but to uphold what his administration regarded as legitimate political and security interests.

He also rejects the idea that peace should be preserved at any cost. In Kennedy’s formulation, avoiding conflict is important, but not if doing so requires abandoning political freedom or accepting coercion. The quotation therefore presents peace and liberty as objectives that should be pursued together rather than traded against one another. Its broader message is that foreign policy should seek both stability and principle, using power as a means rather than treating domination itself as the goal.
