Well, I can see only one solution for them: Help America, if they refuse to help America they will probably be in a lot of trouble and if they help America they will be aided by them if Afghanistan attacks them, of course, if they refuse to help America, the american government should see that they're in quite a lot of trouble if they help them and spare them any economical trouble, but I think it might be seen as though Pakistan is supporting Afghanistan if they refuse to help America.
