Trump gets a new wife every few years ; it's rumored his next wife will be Japanese so there may be a branch Whitehouse in Tokyo soon.
Russia's military is still in horrible shape from when the country went bankrupt. Experts say it would only take Japan about 3 weeks to defeat Russian if a war took place. Don't be fooled by Putin's silly propaganda .
I agree with you about Russia, their military is in shambles compared to back in the Cold War. However how would China fit into this equation? China's military is big, but not the most advanced or organized. They just recently got a central command system and they do not have much war time experience. How would Japan fair in a war with China?
