I recently watched First Blood part 2 again and although it's a movie and not exactly a history documentary, it got me thinking. Suppose that somewhere in the 80s (which would be during the Reagan administration) information leaked that there were still an odd couple of thousand American POWs left alive in Vietnam. Is this plausible (keep in mind it's a jungle the size of Germany)? If so, what would the repercussions of this news hitting the streets??? (or at least getting out to Reagan and his cabinet). What would Reagan do? Threaten war to get the POWs out, go oil embargo on them or what?
