Fatah's most famous attack was the Munich massacre, which if you type into Google enough times will make Mossad agents blow through your door and drag you away to "The Farm."
And it doesn't look like this at all.
Fatah, incidentally, is Arabic for "conquest by means of jihad." What's not peaceful about that?
So basically, after decades of murder and mayhem, Arafat decided to call it a day and retire. And for that, he won a Nobel Prize. Summing this path to Nobel stardom up rather nicely, Reason Magazine suggested, "Start an NGO devoted to murder and mayhem-something on the SPECTRE/Al Qaeda/Medellin Cartel model-and then agree to a truce."
