I doubt even india can project power that far from its homeland, let alone pakistan. And this is in the very improbable case that pakistan happens to be stupid enough to heed to the calls.
Pakistan's defensive forces are designed to resist, and mainly fight a regional war. If pakistan had ever planned to fight a war far away from our borders, paf would have long-range double-engined air-superiority fighters, long-range bombers, and a vast logistics setup for mobility including a heavy air-lift capability. But we don't. Meaning that our planners never intended to engage in such a scenario. So our forces are only meant to play with india, and india alone. And that too, in a defensive battle.
Secondly, pakistan is in a process of recovering from the zardari era. Pakistan has a long way to go, and a huge potential in economical development, and thus that is our prime concern right now. We'll become a regional powerhouse, and a regional transit hub, and a catalyst to regional development in all of asia, including india. IA.
