The Tamil Nadu incident took many by surprise. You can associate Tamil Nadu with extremism of some kinds but Islamic was definitely not one of them. A significant amount of Tamils have deep sympathies for LTTE even today and mild? hatred for Hindi and Hindi speakers but this was completely out of the blue. It's neighbouring state, Kerala however is a different story. With highest per capita migrants to Middle East who return every year or two with a lot of money and radical world view, it is a caliphate in making. Supposedly "secular" parties ruling the state is another great catalyst.

There are many proponent of the “Gazwa-e-Hind” story which is based on an alleged hadith which allegedly predicts a final battle in India and as a result, a conquest of the whole of Indian sub-continent by Muslim warriors. Pakistan Army’s lower and younger ranks are getting even more radicalised than its older generation and it readily accepts this “hadith” as their “destiny” to achieve. These younger generations will lead the Pakistani Army very soon.

Another point I would like to touch is the one mentioned about the rise of Hindu right wing. I was out on the streets about two months back canvassing for the BJP candidate in the local elections, the effect is so massive no sane man will disagree. What most right wingers know and repeatedly avoid saying is that it is not right wing but so far right that the right wing looks far left to them. The sheer over compensation for the last 10 years is mind boggling.

All of this when the guy who brought them to the power (Narendra Modi) is working so hard that a desi IT guy working on sundays looks lazy in front of him. For every time he promises that development he will bring will be shared equally by all communities, some part time holy man and a full time politician will say that we will bring down the mosques and such.
