You are deluded if you think there was no connection between OBL and Saddam. Even the 9/11 Commission Report has to admit there were growing ties going back a decade.
Zaquari had set up his terror network in Iraq as early as 1999. We are fighting that network today as well as terrorists from Iran. Ansar al Islam was an al Queda camp in the north fighting the Kurds on behalf of Saddam. Al Queda terrorists were trained at Salman Pak by Saddam's secret police.
While Wahhabism is a problem it is not the only Islamic group that is confronting civilization nor is the US ignoring its contribution to the problem. Saudi Arabia has been killing and jailing these scumbags as has Pakistan but there are MANY Islamic killers who have nothing to do with the Saudis.
You and MOOer can attempt to make the enemy Saudi Arabia but that is a distortion and misleading simplification of a much more complicated situation.
