Starting when Clinton sent Richerson to OPEC to ask them to raise oil prices so russia could charge more and pay off the loans clinton gave them. The economy of russia and the price of the dollar and oil were pretty much tied together. It became an oil based economy screwing the western european countries.
Oil has dropped below 100, their economy is screwed also, their recent activity in Georgia makes trade a problem for them.
At least the market there understands the situation.
Foreign investors have been pulling out of Russia since the invasion. Putin wrote a check he can't cover.
