I don't think it will happen that way. The US are already being criticised for killing some UN workers by mistake. I don't think the US (or Britain etc) get their jollies from killing innocent people, unlike the Talibarn which seem to revel in it.:(
You know, somebody actually complimented me on my driving today. They left a little note on the windscreen. It said, 'Parking Fine.'So that was nice.
