You already have fraught negotiation and engagement processes right now surrounding the extent of Ukraine's integration in the Single Market that involve opposition stoked by various Far Right groups over agriculture and migration. That would extend into postwar planning and debate

But the migration angle is also about the war because it's about new arrivals of refugees. And even then outright opposition is quite limited. I agree on agriculture but that was always going to be an issue, don't need the far right to agitate for it
