It is alleged that when the Russians invaded Afghanistan, the West "smuggled" weapons to the Taliban. Those same weapons were the ones the Taliban then directed at our troops!
So, as far as I am concerned the West should leave the warring factions in Islamo-land to get on with it. The middle east has enough warring factions to keep them all busy for several lifetimes, and with all the suicide bombers, "paradise" will have long run out of "virgins" if each bomber gets 72!
The only time the West should get involved is if our freedoms are threatened, and then it HAS to be an immediate response, with no quarter for the perpetrators.
