So...I've known about this stuff for awhile, but I thought I'd throw this out there as a possible bunch of dominoes that could've fallen into a Second Korean War.
The whole "hostile fire zone" thing kind of makes me wonder just how serious the US military was. If that's anything like free fire zones, then they were ready to drop the hammer in that one area of the DMZ.
In any case, I just thought I'd throw this stuff out there.
November 2, 1966: KPA ambush on UN patrol, 6 US casualties, 1 South Korea casualties
During this period, KPA conducted large scale infiltration activities which resulted in a series of firefights and artillery duels across the length of the DMZ. The intensity of the hostilities were such that on April 1, 1968, the Department of Defense on the recommendation of General Charles H. Bonesteel III declared the DMZ-Imjin area as a hostile fire zone. The activities extended to infiltration along the coast of the Korean peninsula such as the Ulchin-Samchok landings.
