Psychological projection at its finest...

Russia's now claiming that we, and Europe, are attempting to isolate them, to put them "behind thick walls and an 'iron curtain.'"

Bullshit.  It's their own behavior that's isolating them.

Though the Russian government may try to deny it, they are sliding back into their authoritarian ways.  They are the ones reverting to the behavior that had the free world afraid that the USSR was going to become large enough, and powerful enough, to devour everything.  They are the ones that are silencing the freedoms of speech and the press that the free world holds inviolable.  

Russia claims that the US, EU, and NATO are forcing them back, and building the iron curtain anew, when in reality, they're the ones holding and using the welders, rivet guns, and iron sheeting.
