The concept of "Peace Through Strength" is based on the premise that possessing immense military and economic power is the best guarantee for avoiding wars. The objective is not aggression, but rather "deterrence"—intimidating adversaries to discourage them from considering any assault due to the dire consequences.
Proponents of this philosophy believe that weakness invites aggression, whereas strength compels others to pursue diplomatic solutions. In short: "If you want peace, always prepare for war."
