The Korean War ended with an armistice, not a peace treaty — that distinction matters

The Korean War technically never ended. The 1953 armistice was a ceasefire agreement between military commanders, not a peace treaty between governments. North and South Korea are still technically at war.

This isn't just a legalistic detail. It explains why the Demilitarized Zone is still one of the most heavily fortified strips of land on earth, why the Korean peninsula has the highest density of landmines anywhere, and why every inter-Korean diplomatic episode is so fragile — there's no foundational peace agreement to build on.

The "forgotten war" label has always irritated me as a historian. Three million casualties, Chinese intervention, the first large-scale use of jet aircraft in combat, and a strategic outcome (a divided peninsula frozen at roughly the same line as before) that defined East Asian geopolitics for 70 years — that's not forgettable. It's just that the Cold War narrative overshadowed it, and for Americans it sat awkwardly between World War II and Vietnam.

The armistice-not-peace distinction is the lens that makes current North Korea policy actually legible.
