I think that given enough time all of them will. Socialism is literally the only way to structure a modern society absent exploitation of the global south. Socialists/ML’s have been yelling this for years but now the G7 countries are about to learn the hard way. The Global south is standing up like China did and the West must adapt or die (recede to a subsistence sort of propaganda/physically imposed feudalism).

Well, Spain, Italy, and Greece have already been betrayed by the EU. Greece is quite radical and has a strong communist party.

Then there’s Eastern Europe, which has also been looted by North East Europe since the 1990s, and most of the people never wanted to abandon the Soviet system. Now, that’s an ageing demographic, but those voters are still around and may still be working.

The younger sections of Eastern Europe could be persuaded easily enough to rebel against Western Europe considering their homes have been gentrified and Western Europe has demonised and used them as cheap labour for 30 years.

This is only the factions of the working class.

There will be factions in the capitalists who are unhappy with doing the bidding of the US empire and who will see war as an opportunity to gain or regain their own empire. That would have it’s own negative consequences, but it would weaken any imperialist alliance.
