Incorrect, there are lots of people in the West with a vested interest in keeping this war rolling. We're selling guns, doing R&D, Europe now buys its gas from America (at a higher price) instead of Russia, Zelenskyy does not need to face election.
Groups of people in the West are benefiting massively. Most Ukrainians are not. Most normal citizens of Western countries are not, we're shouldering the cost in rising cost of living, elevated military spending.
We have a hot war on our continent. I repeat, this is very fucking dangerous. WW1 was a brutal, grinding land battle with immense costs for all its European participants. It also led to WW2, which culminated in the absolute decimation of European cities and the eventual use of nuclear weapons. This is the path we're retreading.
You continue to personalise this around Putin. It is incredibly naive to think that Putin disappearing will resolve the problem. It will not.
