Russia should be stretched from Alaska up to Scotland.
Aha... Russia is everywhere. :) Everything is Russia except for China.
As for possible Chinese invasion there were many good points made. I have to say the issue of China is clear for both people and government (Kostia is an expected exception who's always having fun). While studied Chinese missiles at the university our teacher who himself spent his youth in Habarovsk said: "Kitajci, kak sarancha". Which is "Chinese are like locusts". They don't know the word "enough". I don't think there's a room for serious cooperation or (and) assimilation. We're too different (thankfully) for both these. Hard to look for culture in the nation that considers quite ok to eat abortus fetus in 21st century.
Russian policy should be like being polite (not too friendly) and constantly watching her six (back) unless we wanna be backstabbed one day which is likely to be the last day. And I'm for cooperation with the "West" in case the day ever happens.
P.S. Const made one good point though... or well was about to make it. I'd prefer to see more Poles in Russia. Of course on the voluntary basis... in case some would recall our not the best past.
