That order was defined by the tension between the east and the west during the cold war, and it can't be overstated what an existential threat communism was perceived as by the west during this period.
Half a century of American politics were based on the premise that if the US did not win against the Soviets, the entire world would live under a world wide oppressive communist regime. Freedom would be a historical footnote.
This meant that the US urgently needed to have its shit together at all points, not just function well, but also look good. The war against communism was fought in the hearts and minds of the world's population.
Since the Soviet union fell, and with nobody to keep the US honest anymore, it's arguably let itself go.
In part it's metaphorically stopped sucking in it's stomach, to hide its flaws and present itself as flawlessly glamorous. Some of the American decline is problems that have existed for a long time that have now been brought to the surface; but I think the lack of competition is also just as big of a factor.
New powers have emerged in the vacuum left behind the Soviet union, yes, but these are all knock-on effects, and I don't think they're perceived as the sort of existential threat as the communists were. Some are trying to paint them that way, but it's not nearly the same.
“I’m worried WW3 is coming… best we destroy our alliance between the wealthiest and most powerful nations on the planet first!”
Brilliant strategy.
Aka you probably should he worried about exceedingly damaging deranged behavior on the part of an individual who is bent upon expanding the powers of the already most powerful office in the land.
It will cause lasting damage.
Trump has already managed to unify all of latin America against him. Bullying will have consequences, and creating enemies out of friends is a very foolish path.
If cost savings were the true concern, there are many less harmful ways to effect them, so don't give me a story of necessity. The belligerence and cruelty is intended.
The Latin America stuff is not bullying. Look at Colombia, Petro's government collapsed after his stunt because even his own government knew he was stupid and picked a bad fight.
Cost savings is just one of the concerns here. A lot of bad things happen downstream of these US Taxpayer funds, including NGOs who use those funds to enable mass illegal immigration.
I'm a Canadian so I'm biased on the topic but it seems what Trump is doing to Canada is completely unreasonable.
Trump-Americans are indeed rejecting the post-WWII world order. It is no longer serving us.
Trump is renegotiating the deal with the rest of the world. It could blow up in our faces or we could end up in a more favorable position.
