I've thought about that, and I'd think it depends on the place.
In the west (UK, US, Canada etc.), I assume there are various ideologies. I think perhaps more neoliberal ideas in terms of interventionism and such (having seen the need for intervention to stop very bad things), but I'd think there'd also be somewhat of a leftist movement too. However, probably not that many changes.
France I imagine having quite unstable and divided politics, with both remnants of Vichy far right and leftist movements being powerful and perhaps quite militant, all under the framework of a shaky democratic republic, since the whole civil war thing after a long period of fascist rule.
In Germany, i expect far right movements to be illegal and actively stamped out, with any far right political leaders being imprisoned. Probably somewhat of a leftist counterculture by people growing up during and after the Nazi collapse.
In Slavic Eastern Europe, I imagine Slavic Nationalism being a pretty dominating force. Perhaps in Russia, it could be combined with a measure of Soviet-nostalgic leftism. Anti-German sentiment would remain a big thing I imagine. Relative authoritarianism might remain in some of these states, especially Russia, even if there are official democracies.
