The ungoverned globe
I read this entire article and I need some more time to digest it, but I'm ending up in a different "end game" than the writer does, which is interesting because I think they explained the road we're on very well ( i.e. the nationalists and radicals ). Assuming we're accurately dissecting political speech from policy, the "Liberal Order" is in better shape than it's ever been with international conflicts simmering down quite a bit ( USA is even trying to get out of Afghanistan ). So I find the article's finer points to be interesting and maybe accurate, but the meaning/ramifications of this I'm not sold on. Life in the UK is not remarkable different though politically it's gone through the wringer. Same in the USA, the political expression is out sizing the problems. The question is will the tail wag the dog, will politics bring us under whereas the economic malaise the article discusses wouldn't otherwise. Hell, the USA economy took a serious hit from the pandemic and yet, most of life is still going ( for now ) - I'm here typing this shit, not losing my home/job, etc. Not saying it's all coming up roses, USA may well fall off a cliff if the 30 million unemployed can't get back to work pronto, but for now the tensile strength of the liberal order appears impressive, it's taking some serious blows and yet still goes.
In short, my point is, the world economy is growing with technological proliferation/saturation ( everyone has a cell phone, rich and poor alike ), so problems will appear bigger like the USA national debt, but the numbers are just getting bigger and it may not be a big deal. As the article mentions, Brexit turned out to be a nothing burger. The USA 2020 election will be where the rubber meets the road, if the election is contested and the Supreme Court behaves differently than it did in 2000 ( i.e. did nothing and declared the winner from the first vote count ) or the President doesn't leave office in spite of a clear loss, then the concerns of the article will prove true. If Trump wins or if Biden wins and is able to transition into office without much fanfare, then the article's conclusions is incorrect - and simply put, countries have problems, liberal order or not. The economic prosperity outweighs the loss of representation in my opinion - nation states probably shouldn't have larger voices than they do with trade outcomes as that would lead to bigger problems. The fact that nation-states have to accept net economic results is a good thing, driving improvement and change so they can be competitive. There's natural balancing that takes place anyways, if you have a trade deficit, your money devalues making your exports more attractive and so on.
We have problems, big ones. But what having problems is a liberal order problem is not clear.
