"Omar Torrijos, the President of Panama... had signed the Canal Treaty with Carter much... It was a highly contended issue. And Torrijos then also went ahead and negotiated with the Japanese to build a sea-level canal. The Japanese wanted to finance and construct a sea-level canal in Panama. Torrijos talked to them about this which very much upset Bechtel Corporation, whose president was George Schultz and senior council was Casper Weinberger. When Carter... lost the election, and Reagan came in and Schultz came in as Secretary of State from Bechtel, and Weinberger came from Bechtel to be Secretary of Defense, they were extremely angry at Torrijos — tried to get him to renegotiate the Canal Treaty and not to talk to the Japanese. He adamantly refused... He had his problems, but he was a very principled man. He was an amazing man, Torrijos. And so, he died in a fiery airplane crash, which was connected to a tape recorder with explosives in it, which — I was there. I had been working with him. I knew that we economic hit men had failed. I knew the jackals were closing in on him, and the next thing, his plane exploded with a tape recorder with a bomb in it. There’s no question in my mind that it was C.I.A. sanctioned, and most — many Latin American investigators have come to the same conclusion. Of course, we never heard about that in our country."
