>"If you look at the world around us and review the history of terrorism, most of it's been funded behind the scenes by one of the major superpowers, and you can't overlook the fact that a large portion of this has been by backed by the US."
While this assertion is not completely baseless, it's simply not correct, but is the kind of empty-headed moral equivalence that gets tossed around to unanimous approval among a certain class who consider a shibboleth of sophistication.
To wit, in the history of terrorism, we see the Irish Republican Army, The Tamil Tigers, the Red Brigade, the Weather Underground, FALN, Baader Meinhof group, the Symbionese Liberation Army, the current Chechen groups, the Hindu and Muslim groups prior to the formation of Pakistan, and frankly many more -- all without super power support. While some national actors have stepped up to support terror groups, superpower, or even great power support has been the exception rather than the rule.
During the cold war, the USSR, the US and China fought a number of proxy wars, and supported opposition groups in various national civil wars, mostly in Asia, Africa and Central America. Additionally, the CIA engaged in specific assassinations of political leaders largely in Latin America but not really what anyone would consider terrorism by the current definition. You're statement that a large portion of terrorism has been backed by the United States would require expansive definitions of 'large portion', 'terrorism' or 'backed' to be true.
