You don't know that Russia has to sell it's oil under the official oil price because of sanctions?

Other:

Euro/dollar vs. Rubble

NATO added a bunch of strong countries ( eg. Finland)

CSTO => failed

Inflation rate in Russia, eg. Food

Decreased military exports abroad

The requirement to get help from Iran and North Korea

Depleting tanks

Unemployment rate in Russia ( overheating of the economy)

And weirdly enough, the high rates companies has to pay their employees

I'm more amazed why you would even think Russia is even winning.

Ah, yes, the new government. Who wants a Trump tower in Russia. Lol
