Russia seems to be doing it's best to drag more nations into the conflict in an east vs west type scenario, and to some degree it seems to be working. Combination of NK troops being banded about, China sabre-rattling over Taiwan, India buddying up with Russia, Iran supplying drones etc. Tensions are definitely up, and Russia was the one that really kicked the hornets nest.
The problem I see for the west is that letting Russia defeat Ukraine and annex it would be potentially worse than just fighting long term, Russia would gain even bigger monopolies on resources, and would dominate the grain markets for example. Therefore the only choice is to fight back even if indirectly, and step up the supply of arms and maybe eventually even troops to the defence of Ukraine.
I wish the world was a more forwarding thinking place, so much resource wasted on wars and military that could be better spent on improving the lives of everyone, but whilst these different ideologies clash we must make do with the current state of play.
