Sir: With political temperatures rising exponentially, the political landscape of Pakistan is fast becoming highly incendiary and dangerously inflammable. This is the Pakistani version of global warming. If sanity does not prevail and if necessary steps are not taken in right earnest to cool the political mercury, I am afraid the inevitable, whatever it means, is bound to happen.A cursory look at our past will show that our political class is determined to repeat history. The question that naturally comes to mind is who is likely to gain from a potential political stampede flowing from the political debate becoming increasingly nasty.It is not hard to guess the identity of the winners of this tug-of-war. The terrorists must be gloating over the gross inability of our political managers to unite the nation behind the war on extremism. It is obvious, therefore, that the terrorists will enjoy the last laugh if the nation remains torn at the seams.B A MALIKIslamabad
