Clinton finalized the turn-over in 1993, but the island was first turned over by the Lyndon Johnson administration in June of 1968. Not only that, but the United States had historical claims to the island that pre-dated the Japanese claims!
Johnson has to have been one of the worst American presidents, ever.
It really is hard to determine just which one was the most destructive to America because they all did such a through job of trying to destroy our country.
