Kremlin has miscalculated - Europe was able to largely avoid the intended crisis, while simultaneously Gazprom lost its largest market. The pivot from Russian supplies did come at a significant cost though.
Now that the Western sanctions are strangling Russian economy - if Gazprom wanted to come back to European market - they would be first greeted by billions of dollars of contract charges in arbitration courts.
It has long became obvious that Gazprom will likely attempt to use claims of force majeure to try to avoid financial penalties. And as it became customary for Russia - start preparing fertile ground in the courts of public opinion by planting various stories misdirecting the blame and muddying the waters.
