Any action or reaction (including no reaction) could lead to MAD depending on how you see it. Russia has seen fit to escalate significantly despite basically no change in international posture towards Russia since 2014. Economic actions can be reversed much more easily than military action. Sanctions and frozen accounts have an undo button. Dead people and destroyed cities cannot be undone. I see economic action as the one most likely to have immediate effects internal to Russia that would undermine support for the war rather than bolster it.
