Folks,
lets tone down the chest thumping. Neither side really wants to go to war. While there maybe "media" and public pressure on India, the options are very limited. Speak softly and carry a big stick is what Tiyagi is proposing, however the surprise element no longer exists. Pakistani side knows fully well when it could expect a military strike and potential areas where an Indian ingress could occur. The response would be disproportional on the part of Pakistan to make a point. This point is that while Pakistan allows US certain leeway in going for targets inside of FATA, the same can not and will not be allowed to ANYONE else be they ISAF or India or others. With the US we are tied down in terms of a relationship that actually helps Pakistan while at the same time puts pressure on Pakistan. With India, this complication does not exist. Also the Pakistani nation and security establishment have been very angry and sensitive about the US transgressions against the Pakistani territory but as stated above are caught between a rock and a hard place. This does not exist with regards to India.
Pakistan cannot afford a war but neither can India. Both countries need to talk about this. If there are links of Pakistani groups (I believe evidence is being shared by the Americans), then Pakistan has to take action against these groups. Individuals groups cannot be allowed to bring the nation to th brink of war. Having said that, I think asking for Pakistani nationals without specific evidence and charges against them, its very difficult for Pakistan to do so.
On the part of the Indian media, this talk of military options needs to be curtailed massively. No more jingoism. A couple of Mirage 2000 dropping bombs would result in a spiral that would be much more damaging than the Mumbai attacks.
