I have read some Asian country's (who are friendly with Russians) government foreign affairs required readings that is like 2 year old by now. Those materials say Russia is being cornered. They had no other option to but to invade Ukraine. But with sanctions they are more cornered and are desparate. They thought China would ally would them but China's selective neutrality is making them desparate. Those documents say that Russia never actually deployed their main regiments and only worked with mercenaries and allied country armies.

No body knows how much petro product Russia is producing or who is buying them. Those diplomatic documents suggest treating simultaneously as a black box and a cornered animal. The financial sanctions actually was a double edged sword considering UK essentially blocked all foreign transactions even for international infrastructure investments Russia made to foreign countries and at the same time from a global perspective UK was not seen as a reliable financial partner. So, Russia is desparate, EU is desparate but they are not allowed to sit in a table to negotiate... Because US will not allow that. If a war happens across EU every party invovled will see this is to be positive thing because for the last decade economies has slowed down and political views has become extremely polarizing. A war at a massive scale brings everyone together for their country and economy jumpstarts.
