This special broadcast from February 1968 chronicles Walter Cronkite's visit to the front lines of Vietnam following the Tet Offensive. The special ended with the now legendary personal commentary from Cronkite declaring that the war was unwinnable and that the best option was to negotiate an end to the war. That analysis would famously lead Lyndon Johnson, watching the broadcast, to declare "If I've lost Cronkite, I've lost middle America."
