Indo/Pak issue: Is War ever an option?

It is. But it is meaningless and futile if we make it the ends. As a means to a 'victory', rather than peace. If we forget to ask the aforementioned question: "Will it reduce the overall conflict?", and unless we know exactly HOW. It is choosing the lesser evil.
An analogy can be amputating our arm due to a wound gone bad. Some important points to note:

• Not out of a feeling of vengeance: We go to war out of a sense of regret. Out of sadness, not anger. For anger can never reduce violence. To minimize overall harm, not to inflict harm or to 'teach a lesson'. We do not cut off the arm because we 'hate' it. The question is: "Am I sure this act of violence will reduce overall violence in future, and not increase it?" 
• Not as a pain killer: Most importantly, we do not amputate the arm to 'get rid of the current pain'. We do it to prevent GREATER pain and greater harm that is imminent. 
• Not out of irresponsibility: We don't say 'I am sick of the pain, just cut out the bloody thing!' in a hurry. That's foolish - because we have failed to appreciate that it is part of the same body, and there will be other repercussions. 
• Not acting out of lack of clarity: We do not say 'Whatever happens we will see!!' in a state of impulsiveness. We ask "OK - We wage war? Then what? War against what exactly? What is the objective of the war? What is our exact goal?" 
• Not  being blind to the repercussions: e also evaluate all repercussions and take responsibility for ALL of them. We do not say "So what - it was the arm's fault!!". So it is silly to disown the repercussions by saying "But it was Pakistan's fault!!"
• Not trying to justify the pain: When soldiers die, we can become numb to the pain by citing concepts like patriotism, the greater cause, justice etc all in the name of 'Achieving peace'. Death ends up being glorified, rather than being seen as the sad cost it is. Remember the pain that the soldier's mothers, spouses and children experience is real. Our talks around patriotism, even the respect for the soldiers is just talk. Imagine if your child was on the battlefield. Every death now seems a million times more painful and scary - doesn't it? Rather than a matter of honor? We do not say it's wrong, but we realize its huge cost. We don't want our children to die out of someone's impulsive decision, do we? We pause before we scream 'War!!!'. Suddenly many other alternatives start appearing! 
• Not before evaluating everything else: We don't say "cut off the bloody arm", if the wound affects only the little finger. Why? Not because its good or right, but because we CARE! We don't see just the pain, or blame the little finger - but consider the whole body. Why cut off the arm if we can cut off only a finger? We understand that sometimes cutting the arm is the only option, but we don't do it unnecessarily. We appreciate the seriousness. We are adults.

OK. So the aim should be to eliminate violence, not achieve peace. And war is the last, worst, tragic resort. Now what exactly should be do in case of the Indo/Pak dilemma?
