Where is the proof of Bush I's complicity in this alleged coverup? Perot was bilked out of a lot of money from some people who exploited his sincere concern for the fate of American MIAs. These exploiters use the hopes of family members of the MIAs and their supporters in order to earn a lot of money to conduct bogus rescue missions. The most disgusting ones are those who used to be in the military themselves.
The proof is, he was CIA director and vice president, then president. There were POW's alive in SE Asia long after it was reported that the last had come home. That is proof enough for me.
