You see, you repeat this propaganda you heard on TV over and over again.
In reality it has very little in common with ... reality.
Mearsheimer addressed all that crap in his lecture. That's why I posted it.
Actually, if you go back and listen to Mearsheimer, he says exactly what Moogley said! Russia is a paranoid lunatic misinterpreting Western diplomacy near their "sphere of influence"! Where blame can fall on the West is that they didn't listen to Russia's warning that they are paranoid lunatics and chose instead to believe that they were civilized and sensible! But they aren't!
You can watch the Mearsheimer video again and figure out exactly what he says the west did wrong, or just read the paragraph I just wrote.
When a mad dog bites a child, do you blame the owner of the mad dog, or do you blame the child who stomped into its territory trying to pet it? You can argue that there is some blame to go around but it is the mad dog who needs behavior correction.
