Your army is not useless. They defeated us in 1971. I have first hand accounts. My uncle was sadly posted to your swamp in 1971.
Your army is aware that if they took over. The very next day Primark, H &M, Macy etc would cancel their orders from Bangla and within 4 weeks your country would go back to be it's roots as Bangla instead of a wannabe Pakistan. You would again be half naked, wearing those wraps around your midriff with skinny sticks below, emaciated abdomen and eating watered rice. Famine again knocking at your door.
Is that what you want. Now with full stomachs, you can afford to adopt shalwar Kameez attire, pretend Turkish ancestry and dream of be Ertufrul Ghazi?
