I think the U.S. is trying something new, trying to get the terror groups out from under the thumb of the ISI's tutelage. Like in Iraq where the U.S. did manage to pry most Sunni militants away from the embrace of Al-Qaeda.
But what happened to the 'we don't negotiate with the terrorists' motto? What happened to all the criticism of Pakistan in brokering peace deals in Swat, & Kurram recently? Especially when America is doing the same thing in South & North Afghanistan with different Taliban factions? What's with the double dealing, lying & the hypocrisy?
America says it does not want to endanger Pakistan, as an unstable Pakistan leads to an unstable region. But all its actions have been destabilizing Pakistan, whether that is killing innocent tribals, or letting hundreds of Afghan terrorists infiltrate into Pakistan from Afghan safe havens.
