No I don't think so. Pakistan is very important for us in this long war for many reasons apart from political and geographical ones.
So it would be wise enough to remove the other states sponsoring terrorism first before turning the heat on Pakistan. This way we would make sure that other muslims nation doesn't unite themselves against us. By the time they will realize what's happening it would be too late for them. However if India attacks Pakistan in the meantime then our plan will change. We will have to attack IRAQ almost immediately to confuse other nations before they try to unite themselves. We will have to take the initiatives.
As Mr. Bush has rightly said, "not only will we bring them to justice, we will bring those who harbor them, who hide them, who feed them, who encourage them, to justice." and this war will be fought on all fronts (political,military and other levels).
I don't know why the terrorist states have not already done that. We have told them what we intend to do. And somehow, we expect them to just stand still waiting like little dominoes for the push that topples them over. The terrorist states can't be that stupid.
