War & Peace Quote by Ronald Reagan

War, in Reagan's telling, is not a tragic accident or a clash of ancient hatreds; it's a market failure engineered by states that misread the bill. The line is built like a warning label for policymakers: aggression happens when the expected costs are low, when deterrence is weak, when enemies think they can grab territory or leverage without paying in blood, money, or legitimacy. "History teaches" does rhetorical heavy lifting here, laundering a controversial strategic doctrine through the authority of the past. It's not an opinion; it's a lesson allegedly engraved by repeated catastrophe.

The subtext is classic Reagan-era realism, dressed in plainspoken moral clarity. If war starts when aggression is "cheap", then peace requires making it expensive. That points straight to defense buildups, alliance cohesion, and credible threats - the architecture of deterrence. It's also a rebuke to what Reagan and his coalition framed as post-Vietnam drift: hesitation, ambiguity, and the kind of restraint that can look, to adversaries, like permission.

Context matters. Reagan governed at the icy peak of the Cold War, selling a strategy that mixed military expansion with a confident story about American resolve. This sentence flatters that posture by implying that strength prevents war, while weakness invites it. The phrasing quietly shifts responsibility away from the aggressor's ideology or grievance and onto the victim's and the world's perceived softness. That move is politically useful: it justifies spending, intervention, and hard lines not as appetite for conflict but as insurance against it.

It's a compact argument for deterrence economics, sharpened into a moral: make aggression costly, or you'll end up paying far more later.
