They have to blame everything on Russia because the historical precedent has been set (Cold War) that Russia is our foe. In reality, it seems that China is our number one enemy, yet our economies are so intertwined that neither the US nor Chinese government want to initiate the conflict and disrupt their gravy train.
Seems foolish to me to that the government is telling the public that Russia is our enemy at a time when we should be trying to befriend Russia and use that relationship as leverage over China and China's proxy, North Korea.
Russia seems like the easier sell for a military build up while keeping the markets complacent. If we were to shift our dislike towards China, that would disrupt the markets and the Deep State's money supply. Just my two cents!
