U-Turn my arse. Nazis and Islamists have always been bosom buddies. Arafat's uncle, the Grand Mufti of Jerusalem, openly embraced Hitler's final solution.
The antidote for these morons is exactly the same as the one our father's generation used on the nazis-- exterminate the leadership and start working down until they crawl back in their viper's den, Then keep a close watch on the den to ensure they don't re-emerge.
Or, if you're the US government, execute the 20 most flambouyant ones, then smuggle the rest into the country to work for NASA and the CIA.
