The US considers Russia as one of their biggest enemies. Russia never allowed to be subdued or compliant with the rules of others.
One option to subdue Russia would be to use missiles and military bases against it or to try and bring down Putin’s regime from inside.
It has been reported that a color revolution will be used to defeat Putin.
Even though Russia seems to be untouchable, their economy is suffering a lot because of sanctions and the value of the ruble is half of its previous value.
If things worsen, people of Russia might even start a color revolution.
