That, in a nutshell, is how many Yemenis see the US role in their country. The United States “should have never made counterterrorism a source of profit for the regime, because that increased terrorism,” asserts Iryani. “Their agenda was to keep terrorism alive, because it was their cash cow.” The US bombings, he said, were “a bad mistake. Military action often backfires by killing civilians, by the violation of sovereignty. That offends a lot of Yemenis.” For the United States, the most serious question that lingers over Yemen after Ali Abdullah Saleh is: Did US counterterrorism policy strengthen the very threat it sought to eliminate? “It was a major fiasco,” Iryani says of the past decade of US counterterrorism policy in Yemen. “I think if we had been left alone, we would have less terrorists in Yemen than we do now.”
