The Roman empire was still the most successful empire in the world at the time it collapsed.
Nope. Constantople was a tiny city state in 1453. Italy was controlled by barbiarians in 476. Also, the Roman Empire lasted 2000 years. None of those empires were anywhere near the "most successful" when they collapse.
This country cannot and will not survive the already inevitable famines of the 2030’s.
LOL. So Russia is not going to survive another 10 years even? Wow, I suspected as much, Ivan. Good thing my country is the most successful country in the world. We'll try to help you guys over there after Putin in put in prison.
