It is dangerous to EU citizens who are on the receiving end of a campaign to radicalise national governments with far-right Russian-funded puppet regimes which will - clearly, as we can see in the US - be absolutely hostile to existing freedoms.
They feel like repeatedly the baby was thrown out with the bathwater wrt migration and the like despite popular opinion being very much against those. Often getting no genuine choice of opposition that wasn't fringe right.
Now I know so many people who will in turn throw out the bathwater containing their national or supranational interests, rule of law (that limited their options), etc. People who one will struggle to reach across the isle... and it was utterly predictable.
Or how about making sure the corrupted US society do something about them messing up the world economy because rich people want to be richer and so they bought their governments through once again their propaganda arms of all the social media and news corporations they bought?
What about the parts where the US would bomb constantly the ME thus making the people living there want to move out. But of course they won't go to the place that bombed them, especially since there's a whole ocean between them so instead they come to us in the Europe. Oh and if it's not bombs, it's global warming anyway, another thing the current US government pushes hard for.
