Russia's move here is in consideration of both their short and long term oil and gas goals, which are crucial to their economy. Do you really believe that Russian energy will not find a way onto the global market? Has sanctioned stopped Iranian oil from getting to market?
If you want to blame anyone for his move by Putin, blame Germany---especially Merkle. When Germany decided to shut down their nuclear energy production in a misguided environmental move; assuming to rely more heavily on renewables, it meant they would fall short of that goal and then be forced to buy MORE Russian gas. Something Donald Trump warned about it but was ignored.
This is why our global security in the west had moved to making MORE oil and gas production from the USA, Canada, and even Mexico where that was possible. Russia is a energy PRODUCING nation, and as such somewhere in the world their oil/gas is GLADLY wanted. But liberal progressive environmental lunatics would rather cripple Western Democracies in this all out rush to "save the planet" while giving POWER to the worst players in the world like Iran, Russia, China---and yeah, Saudi Arabia.
When Biden showed weakness in the Afghanistan withdrawl, he invited Putin to act boldly. Now wait for China to move on Taiwan... you know they are dying to that sooner than later. China takes Taiwan and then all of use will be wondering where to get our semi conductors from, and Putin won't be the one to worry about us shutting of technology exports, China will control most of that.
