Saddam Hussein was a major anti-Wahhabi activist and pro-Christian too. He has fought Iranian theocracy before anyone else either. How he was punished for a 9/11 performed by known Saudi Wahhabis is beyond any sane logic. Not to mention his demise gave way to power for said Saudi-backed Wahhabis in Iraq.
Saddam Hussein was provably involved in the anthrax attacks which followed 9/11. That likely has something to do with it.
