I hate this site, but they have a decent list here plus some other links. Don't forget the daily terrorism in Israel. That is another battle to fight with your lefty friend.http://en.wikipedia.org/wiki/List_of_terrorist_incidents#1970s
( Please note ~ these are from the internet archives files, so not all pages may be available
IMHO, it's one of the best lists in the net.
Global jihad bump
Tabari IX:69 Arabs are the most noble people in lineage, the most prominent, and the best in deeds. We were the first to respond to the call of the Prophet. We are Allahs helpers and the viziers of His Messenger. We fight people until they believe in Allah. He who believes in Allah and His Messenger has protected his life and possessions from us. As for one who disbelieves, we will fight him forever in the Cause of Allah. Killing him is a small matter to us.
What is Jihad: The Arabic word Jihad is derived from the root word Jahada (struggle). Jihad has come to mean an offensive war to be waged by Muslims against all non-Muslims to convert them to Islam on the pain of death. Jihad is enjoined on all Muslims by the Quran.
