Why is it a bad thing if Sunnis are engaged full-time in destructing the Shi’ites, and the Shi’ites are returning the affection? When both sides are devoting their time, treasure and manpower to this worthy goal (eliminating Muslims from earthly existence), they are much less likely to be spending resources to promote mischief against the West in general and America in particular.
When any kind of assistance is extended to any regime that supports militant Islamic Jihad, or uses it for their gain in influence in the world, then that only works to the disadvantage of the rest of the world that happens NOT to be Muslim. Muslims do not share power once they gain it. They are the ultimate “My way or the highway” people, except then they go out and blow up the highway.
I’m all for Sunni-Shi’a mutual destruction if they would really limit it to each other, but I think that disorder in Iraq (1) gives Iran much better prospects for moving toward a dominant role in the region, and (2) anywhere that large numbers of Islamist fanatics are schooled in fighting and terrorist techniques increases the chances that they will spill out into other countries over time, as Al Qaeda formed in Afghanistan etc.
I think we’d be better off seeing a stable Iraq that is not a puppet of Iran, but the time for that may already be passed. Obozo and company screwed the pooch, on this as in so many other ways.
