So, your Geo-political importance rests on the notion that in case of NE War (not sure what did you mean by it) we need your neutrality. Now my friend, a quick lesson from history. In 1965, the only link between mainland India and Kashmir was attacked to cut off the entire kashmir from rest of India. This plan failed because the battle of survival was fought somewhere else. So, by the time you feel satisfied looking at your North West border (in case of an war and you are not neutral), you can hear tank rolling at your six. And If your next argument is going to bring the Chinese, hold on a second. India and China are not going to war. Just look at our growth rate. Do you think both the countries are stupid enough to go for war and jeopardize their prosperity?
Sale this 'sovereignty' snake oil somewhere else. Your own countrymen day in and day out complain about Awami Leagues slavery of New Delhi in this forum. And don't confuse Indian constitution with your former East Pakistan's constitution. We are a heavily federalized political system and regional parties hold great strength to keep the center always at toe. Talking about Kolkata. Just come and see. It's a much better city than Dhaka, your capital to live on.India wants a deal on Teesta in your favour. But you will never get it because we will never give it to you. So as long as these lazy, delusional fools are stubborn enough to put a sovereign country in its right place, our legal statues are not threatened to be demolished and our secular bloggers, Hindu & Buddhist monks are safe from hacked to death I don't mind being this side of the border.
