Upon becoming leader of his nation, this guy spit a bit at the USA having way too much power in the NATO sphere, and at first proposed a leadership scheme where France, the UK, and US would have equal power, and then proposed a plan so that in the event of Soviet invasion, his nation could negotiate separately while screwing over the rest of NATO. In 1966, this dude removed his nation's forces from NATO command and ordered all NATO forces out of his nation, a situation that remained until 2009, though the US and his nation secretly worked out a way to integrate his nation's forces in case of attack. Identify this world leader whose hobbies were pissing people (even the Canadians!) off and dodging assassination attempts.
