Pakistan and Blowback

The New York Times is reporting that US drones have killed 60 people at a funeral in South Waziristan. If true, this would make it the most deadly attack carried out by a UAV under either the Bush or Obama administration. I've never understood how drone strikes were supposedly advancing US interests in Pakistan. Everytime I read something about them, there seems to be alot of collateral damage, resulting in civilian casaulties.

I suppose the United States still hasn't learned the principal of blowback. For every civilian or even "terrorist" we kill, we create 50 more. We've seen this happen in Iran, Afghanistan, and elsewhere. The US military doesn't need to be continually involved in Pakistan. We have a national security interest, as the FATA regions in Pakistan harbor terrorists, but coordinated intelligence and police efforts can better combat the problem.
