we don't have one. . .
as for the whole "alpha thing" well Pakistan isn't looking to pick a fight needlessly, it's just looking out after its strategic interests. No crime in that, though obviously if we differ in approach and strategy then the other side would be discontent over it. However, blind blame-game statements --while irritating --have no affect on our sovereignty. It's really a war of words and some psychological pressure being exerted, but Pakistan is used to it so it's kind of become a boy who cries wolf thing. We even have grievences which they dont take into account, so it works both ways.
but as i said earlier, countries generally look after their own interests first. In fact, Pakistan has MORE to do to enact such a policy. For example, we should be placing much higher tax/tariff on the supply trucks that go to Afghanistan via Pakistan. It's unfortunate that we haven't done that already. That is an example of us looking after our own interest. Pakistan and Afghanistan government seem to have some understanding on a good 'exit strategy' -- because 'exit' from Afghanistan is more or less inevitable at some point --as was the case with soviets.
but we digress!
