Ottoman empire 250 years ?? I didn't read the whole book but to my knowledge, it started around 1300 and ended brutaly after WW1. Same goes for roman empire, they make it stop at 200AD, but i've always learned it lastest till 4th century.

With those kind of figure bending you can pretty much say anything you want.

The Roman 'empire' actually lasted almost 2000 years when you take the eastern Roman empire (the Byzantine empire) into consideration. The Roman republic started in 509 BC, the eastern roman empire ended in 1453 AD.

Btw, the western Roman empire ended in 476 AD. The ~200 number you mentioned probably refers to the split of the Roman empire into a western and an eastern part, in 284 AD.

Ottoman empire stopped expanding and pretty much stagnated after about 250 years. America could see a similar fate. With robotics and economy and global problems it can't do much about... even meddle.
