Overwhelming Afghanistan and invading Iraq are hardly comparable to engaging in an act of war with a country of a billion people.

Leaving aside that Pakistan has nowhere close to 1 billion people, I have to say that removing a couple of nukes hardly seems comparable to directly or indirectly killing hundreds of thousands of people.

It will piss off alot of people, true, but if Pakistan implodes, there are no good options when it comes to their nuclear weapons. Having them removed by the US might be one of the less dangerous ones, and might even be supported by parts of the current powers in Pakistan.

All this is of course pure speculation.
