"The U.S. in Serbia? Iraq? Sudan? Wace? Rudy Ridge? what are you talking about?"
Let's see some rules now. #1 Terrorism is when someone kills people with a bomb using a car or his back. People killed are called "innocent civilians". If you have an airforce or wear a uniform it can't be called a terrorism and people who get killed are called 'collateral damage'.
#2 Exception to above rule. The Jewish people tried for 2000 years to get their land back. Now the Irish want their land back too. Both, in the past, used bombs to get the British to leave. Only the IRA used terrorism.
