In the 1960s, the Korean War was still in the relatively recent past. In the 1960s, there was crisis involving North Korea over the course of 1966 to 1969. The DMZ Conflict was relatively low key, and American focus was elsewhere. As it stood, the 1960s were a time of many major crises: Berlin, Laos, Cuba and Vietnam, in addition to fear of Red China getting the bomb (which they did in 1964). And that does not touch on global crises more outside of US focus, such as Algeria, Indian and Pakistan, and so on. The United States navigated those crises successfully, except for becoming mired in Southeast Asia. Given our recent history as an obvious inspiration for this type of discussion, what if the Kennedy and/or Johnson administration, in that long list of crises, had had a problematically, dangerously aggressive North Korea and serious trouble on the Korean peninsula?
