Why would "Europe's survival" be at stake without further integration? Why would Lithuania need to stand up to Russia, China, or the US? (In terms of defense there are military alliances. They have never required political union or giving up sovereignty)
Edit as you added things:
> Also, the National Rally is clearly far-right.
Making outrageous claims does not make them factual.
> It was founded by former Waffen SS-members, for chrissake.
That's the FN that preceded the RN, some other founders were involved in the Resistance, too. That's the typical FUD narrative I mentioned, which takes the situation in 1972 and uses it to describe 2025. Are you saying that the majority of French MPs are Nazis? That's obviously ridiculous. Most US founding fathers were slave owners, so obviously the US are pro-slavery, like the Democratic Party that used to support slavery... Equally ridiculous. Again, today the RN is the main party of the right, nothing more. Their positions today would have made them in Chirac's rightwing government in 1986, not in the FN of the time.
The situation today is more like this: "Why Serge Klarsfeld, the renowned Nazi hunter, says he's ready to vote RN" [1] clearly a little different from your claims...
