What a novel way of asking questions about history! A born idiot should not teach history to a person whose memory contains about 50,000 pages of history, only a part of which is about Ottoman though!!
It seems you have even no knowledge on the Seljuk Turk dynasty.
But, what is this Ottoman military history you are talking about when a part of its economy relies also on exporting cheap goods of garments?
Talk of Golden Bangladesh that begs from Hindu India and Buddhist China, Japan and Korea. How about Christian world helps?
Why the Sky Angels do not come down to build railways, roads and bridges, instead? Why the Angels do not teach idiot Bangladeshis the technology to produce needles for the sewing machines? Why does it import from a Buddhist China?
You are bragging as if BD is another Japan. Never to happen with people on the prayer mats 16 hours a day. No time to study and learn, but always crying towards the Sky.
Vej de Mawla quickly. We have been begging you for the last 1400 years, but you always give everything to the non/Muslims. Why, why and why?
