What the Cold War Actually Teaches Us [2026]

I've become more interested in Cold War history as its echoes in current geopolitics have become impossible to ignore. Here is what I think the history actually shows, stripped of the narratives both sides found convenient.

The Ideology Was Real

It's tempting to reduce the Cold War to great power competition — the same dynamics that have characterized international relations for centuries, just with an ideological veneer. This undersells something important: both the Soviet system and the American-led liberal order were genuinely attempting to build different visions of what human society should be. The ideological competition was sincere, not merely rhetorical. Understanding that people on both sides genuinely believed their system was better for humanity — and had complicated, sometimes valid reasons for that belief — produces more useful history than the simplistic "they were the bad guys" framing.

How Close It Came

The Cuban Missile Crisis of 1962 came significantly closer to nuclear exchange than the official American narrative at the time acknowledged. The declassified records of both sides, and particularly the 1992 revelation that Soviet submarines in the Atlantic had nuclear torpedoes authorized for use by local commanders, reveal that the crisis involved several near-misses driven by miscommunication, technical malfunction, and individual decision-making under extreme pressure. Vasili Arkhipov's decision not to authorize the torpedo use on B-59 is probably the most consequential individual decision in the cold war period.

The Third World Dimension

The Cold War was experienced as an actual, hot war in Korea, Vietnam, Angola, Mozambique, Afghanistan, Central America, and dozens of other places. The death toll in Cold War proxy conflicts reaches into the millions. The framework of "the Cold War" as a bloodless ideological competition is primarily the perspective of the two superpowers who mostly avoided fighting each other directly — it was not bloodless for the populations where they fought.

The Lessons That Transfer

Deterrence works when both sides understand what the other considers unacceptable — and fails when communication breaks down or when one side misreads the other's signals. Ideological competition can coexist with pragmatic cooperation on areas of mutual interest (nuclear non-proliferation is the clearest example). And the internal contradictions of political systems — economic dysfunction in the Soviet case — can be more consequential than external competition.

What I actually think: The Cold War's proximity to catastrophe is underappreciated. We were fortunate as well as careful.
