Well, according to the International Border Laws, you cannot torture a civilian in no man's land. Bangladeshi bull buyers go to India to buy your cows and then they sell it in the local market.
The transportation system is not good, as you can Google it, hence they have to come to Bangladesh by foot. The border gates are opened to them for this. Now tell me, why would you open your gates for trade, and then beat up the tradesmen?
Why would you build a dam, that will strangle a nation with drought, and will take away water, which is a basic necessity.
Why would you surround a nation which pose no harm to you, with barb wires? Why don't I see this being done with the other neighbouring nation, Pakistan? Pakistan shares borders with you too, but why not do this with them also? Is it because doing so will get you guys butt raped with a nuclear war?
The point is not the cyber war, but the reason why it took place and like all the Indians, you guys just reacted typically like ignorant fools and are ignoring the main point here.
