The brain dead students (we can just call them O-bots) don't have any clue how much more difficult they just made their lives. Ukraine gets over 1/2 it's nat gas from Russia at a cut rate contracted price. Russia isn't doing that to be nice, they expect something in return. Instead they got a full-on coup with open invites for EU and America to come get involved.
Every economy runs on cheap energy. Without exception. Putin isn't saying anything publicallh which ought to scare the Ukrainians. If he pulls the trap door on the gas for a nation already teetering on insolvency.....
