Interesting debate on war, and borders. I think Ryan makes some excellent points.
And yes, war in general is declining, violent deaths in general are declining, violent crime is declining, poverty is declining, there are many positive things happening as the borders dissolve, despite the negative news spiral we are constantly in, and the serious problems with large scale immigration in countries like Germany and Sweden. We need to get that stuff right somehow, but closing borders and trying to go backwards is not the answer in my opinion.
There is some backlash to the change with people voting for things like Trump, and Brexit, but as we've also seen, a lot of those things probably wouldn't have happened if it weren't for high level corruption and lies, like the Brexit campaign, the use of Cambridge Analytica and other shady data manipulation, and of course the frankly scandalous activity against Bernie Sanders within the DNC, which to me is the worst of them all, but has apparently been swept under the rug.
