The tragedy of Europe is that all the European left ended up siding with the liberals on the war while the right took an anti war stance. Now as people are increasingly realizing that this war was a disaster for Europe they're starting to turn on the people who have been cheering it on, and naturally end up funnelling towards the right who took an anti war stance from the start.
This once again demonstrates that spineless big tent leftism does not work. People had to take a principled anti war stance from the start, even when it wasn't popular to do so. Instead, they chose to be cowards, and now the right is sweeping politics in Europe.
