I found this on Reddit and I read the whole thing, I thought it was interesting.
The author argues in favour of greater European independence on defence (and less dependence on the US). The article is a year old but I think it’s still relevant.
The author is apparently a journalist with France 24, a French state-owned media company, so you could say that makes him biased in favour of the French position. But I think he still makes valid points.
I suppose that complexity involves international ties, and some voters realise that their jobs are dependent on internationalism, so they don’t want to vote for right-wing isolationism. But some people are happy to vote for isolationism anyway, because they want to reduce immigration in many cases. Who knows what the future holds, but I guess we now have four years of Trump leading the free world to find out.
