Once Russia is done with Ukraine, they can add Hokkaido to Sakhalin oblast.
Russia would get its *** kicked HARD if it took on Japan. Their military is top notch and probably the best in the world right now...even over the US.
I’ve been in exercises with some of their guys and they are no joke. Collectively speaking I’ve never seen better soldiers. Lots of militaries have soldiers who perform at an elite level. With the Japanese it’s hard to find one who doesn’t.
But hey, if you guys want to go dance with them then go for it. They’ll make the Kremlin into a groovy shopping mall if there’s anything left of it.
