Much of the jihadi industry in West Bengal and Bangladesh thrives on liberal doses of funding from Islamic countries in West Asia, particularly the Wahabis.
Kolkata is the financial terminus of most of the insurgent groups industry, the Maoists industry, the jihadi industry (straddles West Bengal – Bangladesh), the cattle smuggling industry from India to Bangladesh, the illegal mining industry and the fake currency industry.
The Northeast has become a volatile mix of jihadi outfits, Maoists, insurgents, the ISI and Chinese agencies. They are all feeding into each other.
The overall manifestation of the geopolitical flux in the Bangladesh – West Bengal region is its descent into hub of jihadi terrorism. Earlier, India blamed Bangladesh for harbouring Indian terrorists and insurgents, now the reverse is happening, not because of the omissions and commissions of the Union Government but arguably because of the commissions of the state government.
