Russia is not so much an enemy as Russia and Russians feel somewhere between a messianic and religious conviction that they must restore Orthodox civilization, and that the west has consistently prohibited their efforts – and the truth is we were wrong and the russians were right.
Russia is paying a very high price for the Bolshevik and Soviet Eras.
We were wrong in entering WW1. Wrong in entering WW2. Wrong not to defeat the communists in China, and wrong not to immediately include the Russians in NATO. We were right to crush Saddam Hussein but wrong to try to create a democracy, rather than let the existing peoples replace him.
Russia merely screwed up invading Ukraine. She could have easily bought all of ukraine other than Galacia (in the west) for a song, and now she has made herself a threat again.
