I hear you, but the US is hardly the only country on the planet that’s had a few disruptive elections, including the EU BTW. Making generational decisions over one presidential cycle is rather short sighted.
When it's Hungary it's funny, because it doesn't matter, when it's the US it's not, because it fucks up the entire world's order. It really is not that hard to understand the problem
While there are troubling developments in EU countries as well, there is also the converse (e.g. Hungary), and the EU parliamentary systems are significantly more resilient than the US two-party presidential system.
Mistakes happen but this same buffoon got elected twice. That's no fluke, deep down the american population likes him enough to give him two chances.
The US is on the path of Russia since the end of the iron curtain, moving to a kleptocracy ruled by (tech br)olichargs.
The electoral + two-party system makes it nearly impossible to break out of this.
Until the USA fixes their broken political system, it would be unreasonable to seek to create major bonds with them.
They will remain a partner, but they should be a minority partner.
