Hexbears have been predicting this as the eventual outcome for 2 years now.

More of a german/french phenomenon than broadly european (though maybe france and germany are the only countries that really matter honestly), in most EU countries the further right wing parties are also pro-war, and here in portugal where the communist party has been consistently anti-war, moreso than dem soc Left Block, including opposing arms shipments to ukraine even, we just get consistently attacked and mischaracterized in the media and I can't say we've made electoral gains from taking a principled anti-nato position, maybe we will in the long run but not yet, it has definitely cost us votes.

Public opinion on the war hasn't soured that much here (fucking portuguese provincialism wanting to be "close to europe"), and even where it has a lot of people are still unwilling to go along with us when we call for something like a political solution.

The only meaningfully anti war Social Democratic Party in my country got like 3% of the vote.

The european left has shat the bed decades ago when they turned from social democrats to neoliberal ghouls. Nobody actually cares about the Ukraine.
