Define 'counter-terrorism'.  

Then decide whether Osama bin Laden's attack was the beginning or whether Iran and Hezbollah on the US Embassy in Lebanon in 1983 was the beginning.  Or the 1972 Olympic games was the beginning.  

Or was the bombing of the World Trade Center in 1993 by Sheik Omar Abdel Rahman and his confederates the beginning?  

Was President Clinton's 75  cruise missile attacks on Afghanistan and Sudan in  August of 1998  the beginning of our response?  

"President Clinton described as an act of self-defense against imminent terrorist plots and of retribution for the bombings of U.S. embassies in East Africa two weeks ago."
