One needs only to look to the past to understand the current conflict that America is in. Look to the Iraq/Iran war in the 80’s. America funded Saddam to the tune of billions of dollars in retribution for the Muslims outing the old Shah of Iran who was nothing more than an American puppet. Look to Afghanistan during the Russian invasion. America, through the CIA, directly funded Osama Bin Laden in the fight to drive the Russians out of Afghanistan. Osama was basically in the employ of America. America still funds the Northern Alliance (drug lords) in Afghanistan.
The invasion of Iraq had nothing to do with weapons of mass destruction, even Colin Power admitted that the day he addressed the United Nations was the most embarassing day in his life. America invaded Iraq in retribution for the support given back in the 80’s and to secure oil reserves. Yes, other countries (England and Australia) were conned into this fiasco. Both countries have since admitted complicity in that the evidence presented was basically false.
Saddam Hussein did have chemical agents to suppress his population, but one must look to the west to determine the source of all the chemicals and expert assistance given (Germany, I believe). Who gave the Iranians their nuclear capability (the French)? When is the west going to understand that one cannot profit by exporting technology to countries with suspect idiology and not get bitten in return?
