I expect that there will be a split between the US and Europe in the coming years. The US sees China as its main adversary, and Europe is losing strategic relevance for the US because Russia is not an ideological opponent the way USSR was.

However, if the US simply left Europe then it would end up gravitating towards the east, first economically, then politically. That would be highly undesirable from the US perspective as it could result in a huge Eurasian bloc with from Europe, to Russia, to China. In my view this is what the war in Ukraine is all about. In fact, National Interest published a very revealing article back in 2021, while it focuses on Russia, it's pretty clear how the argument extends to Europe as well https://nationalinterest.org/feature/strategy-avoiding-two-front-war-192137

The US has also been predating on Europe economically since the start of the war. US companies have been enjoying selling energy to Europe at high prices while Biden's inflation reduction act lured companies away from Europe. Today, Trump is building on this strategy with massive tariffs designed to stifle Europe's economy and lure more business to the US. The threat of Russia is also being used to force Europe into massive increase in military spending, most of which will go to American military industry.

All of this is bad news for Europe economically, and that's creating a lot of internal political tension. As people see their standard of living collapse, they're turning to nationalist parties because the neoliberal center has lost its credibility in their eyes. Hence why we see a surge of support for RN in France, AfD becoming a major party in Germany, and so on. I expect we'll see more of what we saw in Romania where elections will be cancelled, candidates arrested, parties banned, and so on. All of that will further delegitimize the current system as people start realizing they're not living in a genuine democracy.

Unfortunately, the left has been systematically dismantled in Europe since the end of WW2. What I mean specifically is the economic left. Socialism in Marxist terms mean worker ownership over the means of production which is directly at odds with the current capitalist state of relations where private ownership is the norm. Most of what constitutes the left in the west, such as social democrats, does not challenge capitalist relations. These parties simply want to curb the worst excess of capitalism such as having the rich pay more taxes, provide more social services, and so on. These are reformist parties that seek some form of sustainable capitalism.

There are a handful of genuine socialist parties in Europe, but they're extremely marginalized and I can't see how they can break into mainstream politics at this time. One of the problems is with messaging. The right has a big advantage here because their narrative is largely compatible with what people already believe. In a sense, the right is also a reformist type of movement where they're not suggesting any revolutionary change. People who become disillusioned with the mainstream have easy time gravitating towards the tropes the right peddle like immigrants being the problem and taking people's jobs away.

On the other hand, accepting socialist narrative requires accepting that the current system is fundamentally broken and there needs to be radical restructuring of society. In my opinion, what socialist left needs to focus on is crafting its messaging in a way that resonates with the public. The narrative has to be at least as appealing as what the right offers for people to even start to listen.

There's also MERA25 (lead by the likes of Slavoj Žižek and Jannis Ver.). I quite liked them but they (and other pan-euro parties) have no chance of winning seats so long as the seats are distributed within each country separately.
