Why do you need those parts back? Wouldn't been wise of conquerer to head conquering south and touch the bay??? why freaking take all mountains only.We have enough of it ..Do we need more? tell be beside natural beauty - natural beauty (thats what people cry all the time) what is there ?? Mines ? access to third country ? - bhutan - :P Man what we have we cannot handle properly, develop .Whats the point adding more mountains . just the tally of improvised people in Nepal would go up nothing more !!!
