A partial list, representing acts killing 10 or more and also the section with the most diverse outfits for your perusal.
Come 1985 your 'sole' bombers begin to enter the picture more (mainly Al Queda, thanks to Ronald 'Cowboy' Reagan).
You don't help your case by being in denial or being just plain ignorant.
Last anyone who's ever gotten blown up checked, terrorism kills regardless who commits it.
Terrorism bad, mkay?
