Senior U.S. officials insist they continue to have a secret agreement with Pakistan, or at least from the army, to conduct drone strikes. Senior Pakistani civilian and military officials have publicly criticized U.S. drone attacks in the past while consenting to them in private.
But even that agreement seems to be based more on Pakistan's fear of what would happen if it stood up to the U.S. on drone strikes, rather than a real desire to see the program continue. Pakistan relies on the U.S. for hundreds of millions of dollars in civilian and military aid, and even more importantly, for support in getting a $5 billion bailout the country desperately needs from the International Monetary Fund.
Raising this issue at the UN is a bad, bad idea unless it's only public consumption back home after taking permission of the US of A to raise this issue at the UN!
