Correct; when we get out! Fox News was reporting such a death of an American soldier and stated that more Americans had been killed that way this year, than had been in the whole of last year. Seems to be getting worse.
I bet there are no Afghan police or Afghan soldiers around when Cameron or any other VIPs visit Afghanistan.
We must learn not to trust any of these sly murderous scum, and get out now and leave them to kill each other, because that is all they are capable of doing.
In the early 80's the Russians had 115,000 men in Afghanistan. When they realised they could not win they pulled out. The British should learn from history.
