First of all, September 11, 2001 was an inside job so those Americans should not count or at least use an * to denote justified circumspection. Bush-Cheney killed Afghans and Iraqis, over 8 years, with a recklessness not seen since America's genocidal war against Native Americans, but Americans can't be bothered with the blood of non-white skin.
The teary eyes of tens of thousands fawned all over Obama-Biden as some sort of messiah and all they got is more blood, wider wars and domestic destruction. Obama's wars span the world and the killing grows with drones and murderous air attacks by US poodles like Saudi Arabia and Israel using all US military industrial complex supplied munitions.
American subterfuge is responsible for assassinations and coup d'état the world over. Corrupting otherwise progressive governments to impose strict authoritarian rule and other oppressive strategies with which to threaten their citizens. Such draconian policies have forced millions of people to flee their homes and countries for safe harbor and are being met with police violence, in spite of the fact that such refugees are the consequence of American interference in sovereign countries.
Terrorism is the stock and trade of The Ugly American.
