Russian and Ukrainian people are the same Slavic people. But they are being made to fight and destroy themselves by the puppet masters. Russia could have won the war already if they actually made the actual effect to but the powers to be are obviously prolonging it.
And America keeps funding Ukraine to keep the war going as well .
None of this serves any purpose other than to kill as many White people on both sides . Watch this war become a meaningless never ending war with no real conclusion.
Same way they do it everywhere else. Use "international" orgs as cover, foment unrest, advise and supply whatever local oppo org is the most committed/ruthless, take advantage of moments national weakness as opportunities. They wouldn't do a land invasion because nukes.
As for finland in nato look at a map to realize that doesn't matter for Russia's interests.
