What I don't get is why do pakistani's mostly display only suicidal tendencies?, I doubt anybody's buying into your gun to your own head routine anymore, so my advice is it's a wasteful tactics because no one cares about pakistan anymore to intervene on its behalf or negotiate a stand back agreement.
As I said in my post to you, I doubt India is as lowly as the rest to not honor an agreement. I am sure we will stand by it even if it is with a useless entity as we have done it all along.
As for the rest of your balderdash, war isn't fought in cities, it is mostly restricted to borders and between armed forces, so if you wish, you can very well bring in your civilians to fight for you, also chew on the fact that even a 100 billion dollars worth or more of warfare will not faze us while it will decimate pakistan completely, simply because you do not have the resources to match us, and I doubt pakistani army has enough soldiers to reach any Indian major city, and a war between India and pakistan will be a war of attrition and we very well know who has the better chance of running through to the final flagpost on the back of its sheer strength, reach and resources. But in the circumstances that pakistan decides to threaten any major city then the retaliation will be severe and pakistan has just a handful of cities and all of them close to our border and well within reach.
So, I doubt pakistan poses a threat to India's economy, infrastructure or our civilization , literally not much. Nukes are pakistan's safety umbrella and the moment they decide to use it will be an end to its safety.
