Is war an option?

I did not think that things would come to this. When Mumbai happened and the whole nation erupted with anger and lamentation, it seemed that the nation has come together but for what? Now since the grief has settled there's a possibility doing rounds in emails,blogs,smses and the news is as usual filled with it. The possibility of an INDO-PAK war.

Even if I remove the basic fact that I am an Indian, the opinion still exists that Pakistan should have behaved more responsibly not only as a neighbouring state but also as a global citizen. After all which country will deny one of its own sons whose identity is established beyond all doubt.
And yes, I know most of us agree on the theory and know Pakistan should have done better but still I never imagined that in this age , even speculation about a war between two nuclear powered nations could come up.And it has not remained a coffee table discussion any more with the nuclear committees in both the countries having secret meetings, the option seems really an option.

I received an sms which said " vote:  should india go for war? count :  war:69  no war:10 dont break the count".Clearly , we are stretched far beyond our limits.
So should India go for war? What is your opinion?
