Really!!??
"Abdelbaset Ali Mohmed Al Megrahi, a Libyan intelligence officer and the head of security for Libyan Arab Airlines (LAA)......On January 31, 2001, Megrahi was convicted of murder by a panel of three Scottish judges, and sentenced to 27 years in prison." http://en.wikipedia.org/wiki/Pan_Am_Flight_103
"Libya was blamed for the bombing after telex messages had been intercepted from Libya's East Berlin embassy.....In 2001, a Libyan diplomat, Musbah Abdulghasem Eter, and two Palestinians, Yasser Mohammed Chreidi (or Yassar Al-Shuraidi or Yassir Chraidi) and Ali Chanaa were convicted in Berlin's Superior Court of aiding in murder, and Chanaa's former German wife, Mrs Verena Channa, was convicted of murder. They were given sentences of 12 to 14 years in prison."http://en.wikipedia.org/wiki/La_Belle_discotheque
Please get your facts straight before you go spouting off stuff like that.
There is a lot more to the story than Libya giving up terrorism and aiding the US in GWOT, they are destroying their chemical weapons stockpile
http://www.cnn.com/2003/WORLD/africa/12/23/gadhafi.interview/index.html but most importantly they also gave up their clandestine nuclear weapons progam
http://www.cbsnews.com/stories/2004/01/26/world/main595939.shtml and in the process handed over all of the material and info they had acquired in their pursuit of nukes, giving us valuable insight into the world of nuclear technology smuggling and many of the characters involved in that illicit trade. We found out awful lot about the Pakistani scientist Dr. A.Q. Khan and his network from the Libyans

All of this information is very easily accesible on the internet, (while Wikipedia is not always 100% accurate in this case all of the information I cited is accurate), please take a little time to do some reasearch next time before you go off into left field.....Google, it is a wonderful thing......
