Columbia President Bollinger Introduces Ahmadinejad

Just watch it... America's hospitality is outrageously ridiculous and dangerous. Ridiculous is the guy that speaks in this video and dangerous are the supporters of the massacres of the US all these years. Iran is not "clean" but US is far more dangerous for the world than them. Why a flawed nation (as Iran is) cannot have a nuclear program (or even atomic bombs) while a more flawed and dangerous for the global peace US can have whatever they want? Since when they can judge and not be judged?
