More like protocol. You have a set of options on the table and you try the best option first. One: Force Musharraf to fight the terrorist. Second: Ignore Musharraf and do it ourselves. And these options do take time, allowing terrorists to careout their plans. I won't blame India for taking action if the terrorist incursions continue while we are doing these things.
But regardless of Musharraf, the Pakistanis will never allow India to perform military operations in their territory. That's just the reality of it. You act as if the fact that Pakistan has nuclear weapons is irrelevent. Indeed, it is the reason why there is such a huge mess over there now.
Option 2 is is what the US should be doing to wipe out the vermin. OPtion 3 is for India to conduct its own campaign; its called WAR, incursions to another country's territory without their consent.
Well, nuclear blackmail is a recipe for inertia. We'll see what happens. Of course, India, historically is all bark and no bite. Take out the terrorist camps in Kashmir; if the nuclear jihadis escalate, its a risk India has to take. Do you think there's any difference between the taliban, alqaeda, LeT, JeM - they've all been spawned by the ISI and financed by the Saudis.
