from: Britain voices concern over Pakistan-US deadlock | DAWN.COM
I was aware of the visit last week. I also new the Americans were intending to play games like they did yesterday. They only pulled SOME of their negotiating team to flex their muscles knowing William was coming today - so childish i could yawn.
I genuinely believe for the betterment of Pakistan they should say "Thank you but no thank you with your negotiations - we would rather you left and let us be". Do it amicably but do it. Its better for Pakistan in the long run...
