That is precisely we are not able to. We seem to follow the British model in tackling the terrorist menace. Because both India and Britain has one thing in common. Politicians of both countries depend heavily on the minority votes to come to power. So they can not afford to antogonise the minorities. If the police take strong actions and apprehend one or two from the minorities, the community leaders, considered to be moderates start howling 'community in danger', 'community targetted', etc, etc., What more even the judiciary and the half baked intelligentia also joins the chorus. That brings the politicians/authorities in line and on the backfoot.
Actually the problem in fighting terrorism does not lie in tackling the terrorists. But first tackling the moderates and intelligensia. It is these elements which is acting as glucose for the terrorists. They have nothing to lose in any terrorist act. When they utter the soothing words their stock goes up amongst the minorities and position themself in such a way that they become the favourites of all political outfits during the next elections hoping that they can garner the block votes of Minorities.
Recent events involving raids on the houses of some minorities invited lots of criticisms in UK from these elements. And similar voices are commonly heard in India too.
Learn from US, Russia and China. Be ruthless with the perpetrators. No mercy just because they are Minorit
