The president's desire to recast the War on Terror as an "overseas contingency operation," has been effectual only in that it moved the theater of the operation to America's heartland. As a result, American citizens have been forced to become much more vigilant.
Here's a look at the terror incidents -- successful and unsuccessful -- on U.S. soil since Obama's inauguration.
A naturalized U.S. citizen from Pakistan, accused of driving an explosive-laden SUV into Times Square and attempting to detonate it, is arrested at John F. Kennedy International Airport after boarding a plane bound for Abu Dhabi in an attempt to flee.
A naturalized U.S. citizen from Pakistan working as a U.S. cab driver is arrested for allegedly helping al Qaeda purchase explosives by supplying the organization with money.
An al Qaeda-trained 23-year-old Nigerian Umar Farouk Abdulmutallab is arrested after a device he allegedly detonates fails to explode on a trans-continental plane originating from Amsterdam. Abdulmutallab is overcome by passengers who put out the flames and subdue him. He later tells investigators he is "the first of many," apparently unaware that he is actually the fourth or fifth of many.
What is particularly frightening about the "Underwear Bomber" (as he would come to be known) is what might have been. This is the first incident in which a fully-operational bomb, capable of inflicting catastrophic damage, is hampered only by the inexperience of the bomber.
Three men, the al Qaeda-trained Najibullah Zazi, 24; his father Mohammed Wali Zazi, 53; and Queens imam Ahmad Wais Afzali, 37 are arrested in connection with a terror plot to blow up targets in New York City.
A suspected anti-military Muslim convert is arrested for shooting two soldiers, killing one and wounding another, outside a shopping mall.
