Lool So you think Russia is just a peace loving nation, don't you? Lol
It seems you don't even know that Russia and Japan are still technically at war, since they never signed a peace treaty after world war II. you also don't seem to understand that Russia has been sending bombers, fighter jets, submarines etc into Japanese air space/territory, and coast for decades now, moreover they still occupy Japanese islands they seized illegally after world war II and are now calling on foreign I investors like China, Korea, west and even U.S to invest there.lol.
just because you are farrrr away from Russia (hence you faced less threat from them) and you hate/have issues with the Chinese, that doesn't means you should be blinded by your patron Russia aggression/expansionist nature. Mind you if Vietnam was a neighbour to Russia, it won't even exists anymore, it will have been long absolve and incorporated in into mother Russia.
Japan still rightly views Russia as a real/potential threat. Luckily the U.S(along with its alliance with Japan) is there to check Russia's aggression against Japan.
You are one of the very few Vietnamese members I admire/respect on here(with nice guy, but for other reasons though. Lol), please be more realistic in your views like you have been for a long time now.
