Captured it with disregard for native population. Then they tried to "assimilate" them like Saddam did to the Kurds, like the Americans and Canadians did to the Native Americans, like every single tyrannical government did to minorities. But hey! They're dirty Brown Muslims! Shut up you dirty stinky Lungi! I can be racist since you're a dirty Muslim bengali!
LOL, it seems the concept totally eludes you. Each and every place on this planet has been captured by one or the other invading force. You think muslims just popped out of the ground in Central Asia, Northern Africa , Chechnya,Malaysia etc? No , Islam originated in Arabia and then spread outwards , applying a mixture of both peaceful means and of course , some very violent techniques like slaughtering , forced conversions , assimilations etc.
You can't point to a piece of area and say , hey, this land was historically muslim and so it should be now. Like yeah , as if no one lived in these areas before muslims came around and claimed it. So if Russia should vacate Chechnya, then Americans should vacate US and leave it to the tribal Indians, Aussies should also find a new home, 1 billion odd muslims should vacate all the areas I mentioned above and move to Arabia . Yeah , let's just all become refugees
It can also be freed the same way these vodka addicts captured it. USSR dissolution, Kosovo, Bosnia are case examples. The world doesn't revolve around hindutva pagan way of archaic thinking.
Yeah, anything is possible Lungi. Of course it "can" be freed. On the other hand , Russia "can" just send its million odd soldiers and tanks there and eliminate every living being there. The world doesn't revolve around Lungi wet dreams
