India’s 2,582 mile border with Bangladesh is even longer than America’s 1,954 mile border with Mexico.
The two countries are divided not only by that border, but by religion. India has an 80% Hindu majority and a rising 13% Muslim minority. Bangladesh has a 90% Muslim majority. And the tide of Muslim migration from Bangladesh to India began to shift the population balance in some Indian states.
India has spent decades building fences, topping them with barbed wire, and installing lights. The lights are there so that the guards can see. Unlike America, there are guards, they have guns, and they shoot.
