The electricity grid operators of the three Baltic countries on Tuesday officially notified Russia and Belarus that they will exit a 2001 agreement that has kept Estonia, Latvia and Lithuania connected to an electricity transmission system controlled by Moscow.
No I mean Russian economy will not be severely hurt by this.
I think OP is simply cheering that they want Russia’s economy to crumble.
This power grid thing is only a small part of their economy, and OP wants more bad stuff to happen to their economy.
