How are the political climates (in terms of ideology representation in national parliaments in present day Europe?
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.
