Act, Mr PM, Act

The Prime Minister has said, yet again, this time in the context of the bomb blast at the Delhi High Court, that "we will not succumb".
So we are expected to go around our usual business - breakfast, office, household chores, school, college, back home, saas-bahu serials, trip to the mall, dinner and bed. Just to tell the terrorists that we are not "cowed down". 
But why not show that we are not "cowed down" - and the steely resolve with which those words are said - by carrying out the death sentence on Afzal Guru, Devinder Pal Singh Bhullar and Rajiv Gandhi's assassins? And fast-tracking the prosecution of Mohammed Ajmal Amir Kasab?
Wouldn't that be a better way of showing India will not tolerate terrorism in any form? And that terror attacks cannot be used to blackmail us into inaction (in this case stopping the hanging of Afzal Guru)?
In fact the latest terror attacks should be used to tell political and other groups pleading for clemency to these above-mentioned worthies (for that is what they are to these groups, never mind that each of them has indulged in senseless killings) to stop pleading their case. They never showed any mercy to the people they killed, why should they be shown any mercy?
Does this sound churlish, immature? Perhaps.
Should I exhibit more sagacity and moderation? I see no reason to.
I see no reason why India should come across as a soft state, which people can come and bomb at will.
There is a time when sagacity and moderation have to be set aside. This is such a time.
Of course, there will be the usual arguments against death penalty itself. But as many people have pointed out, why does death penalty get debated only when high profile or political convicts are involved?
Perhaps there is a case against death penalty. Perhaps there isn't. Perhaps we need to debate it.
But after Guru, Bhullar, Rajiv Gandhi's killers and Kasab are hanged.
