Russia invades a neighbour who dares to attempt to have stronger ties to the west.

You mean a western led coup with assistance from neo nazis to remove the democratically elected government of Ukraine in 2014. With the explicit goal of "Latin Americanising" Eastern Europe and privatizing and selling off all their assets. The Ukrainian government still has a website up today for selling off anything not bolted down to the highest bidder. Shock doctrine 2.0.

West supplies neighbour with weapons to defend itself.

You mean forcing Ukraine to start a counter offensive using NATO combined arms tactics for witch Ukraine had neither the equipment or required training to execute. And with no will from the west to give Ukraine the required equipment (F-16 saga anyone?). How do you do a combined arms offensive without a fully functional air force? The worst part being that the west knew this, and still forced Ukraine to go ahead with the offensive anyways, knowing there was little chance of success.

Tankies on Lemmy: "oh no, Russia is being oppressed"

More like people saw this coming and think the loss of life over this attrition war is tragic. How does Ukraine win an attrition war against Russia? What is the exit plan? This is just Afganistan all over again in some ways.
