The Taliban has attracted additional money, and suicide bombers, from Arabia. Two years ago, most of this support shifted to Iraq, where al Qaeda believed it had a better chance of winning some kind of victory. But too many Arab terrorist resources in Iraq produced nothing, and Iraqis have become very hostile to al Qaeda as a result of all the Iraqis killed by terrorist attacks. So now, efforts are shifting to Afghanistan. However, this is also a hostile environment for Arab terrorists. Moreover, Arabs stand out more in Afghanistan, where most Afghans are European or Central Asian in appearance (the majority Afghans belong to ethnic groups related to the ones that invaded Europe thousands of years ago.) Afghans have been quick to turn in suspicious Arabs, or any suspected terrorist activities.
Recall that the money men shifted support to Iraq when Afghanistan looked like a loser. Now it looks better relatively speaking after the drubbing the jihadis have received in Iraq.
I guess we aren't the only side in this war whose supporters want to bug out of Iraq.
And I again have to wonder about a loyal opposition that wants to save an enemy already convinced it will lose to us and in the process of disengaging from the war.
