Highly recommend Heather Cox Richardson’s free Substack. She daily sums up current events in an old-fashioned, straightforward, journalistic way* with all her sources listed at the end. There’s a text version and an audio/podcast version. There is a paid subscription available but I’m satisfied with the free one.
I found today’s post particularly informative and dismaying.
Some excerpts, but do read the whole thing.
How it started:
…It was begun in 1963, at the height of the Cold War, to be an independent venue for experts and policymakers to discuss the most pressing security issues around the globe.
While the USSR absorbed neighboring countries as satellites, the U.S. and its allies and partners embraced a theory that international relations could achieve permanent peace so long as they emphasized representative democracy, economic interdependence, and international organizations. The equality, shared norms, and costs for wars that this system built, the theory went, along with new mechanisms for negotiation, would prevent global military conflict like those the world had suffered twice in the early twentieth century.
How it started to go wrong:
Since World War II, those values have reinforced civil rights and created opportunities for women and people of color, created dramatically higher standards of living around the globe, and prevented global wars. But the collapse of the Soviet Union in 1991 changed global calculations. Rather than defending the tenets of democracy, American leaders focused on spreading capitalism into the newly accessible states, arguing that democracy and capitalism went hand in hand.
At home, the end of the Cold War meant that the extremist Republicans who hoped to destroy business regulations and slash taxes, as well as halt infrastructure projects and end civil rights protections, no longer had to work with Democrats to stand against the USSR. They focused on getting rid of those they called the American “left,” a term that for them included not just Democrats but also Independents and traditional Republicans in the mold of President George H.W. Bush, who believed the government had a role to play in regulating business, providing a basic social safety net, promoting infrastructure, and protecting civil rights.
Skipping a bunch of stuff here that I wish you would read. But here’s where we are now:
When he opened this year’s conference, German chancellor Friedrich Merz warned the Trump administration that “[t]he leadership claim of the U.S. is being challenged, perhaps already lost,” and that the world of great-power rivalry the U.S. is trying to set up will leave the U.S. alone and weakened.
It gets worse. Enter Marco Rubio (snipping heavily):
In his speech to the conference yesterday, Secretary of State Marco Rubio was less confrontational than Vance was last year, but the message was the same. He attacked all three of the pillars on which the U.S. has previously stood in foreign affairs. Global trade has ruined the U.S. economy, he said, while international institutions have undermined sovereignty, and “a climate cult” has imposed energy policies that are “impoverishing our people.”
He focused, though, on “mass migration,” which he claimed “threatens the cohesion of our societies, the continuity of our culture, and the future of our people.” He called for Europe to join with the U.S. in rejecting the tenets of the post–World War II vision, claiming that “[w]e are part of one civilization—Western civilization. We are bound to one another by the deepest bonds that nations could share, forged by centuries of shared history, Christian faith, culture, heritage, language, ancestry, and the sacrifices our forefathers made together for the common civilization to which we have fallen heir.”
His description of that shared heritage reflected the Trump administration’s fantasy past. It was all white and Christian……
Rubio’s version of the U.S. did not include Black Americans at all……
Entirely ignoring the threat of autocratic Russia against Europe, Rubio pushed Europe to abandon the values of democracy in favor of imperialism. He said the U.S. had “no interest in being polite and orderly caretakers of the West’s managed decline” and urged Europe to work with the U.S. for a return to western “dominance.”
…
To which one can only say, “What the ever-loving FUCK?”
Burn those bridges, Little Marco! Burn 'em down, you bastard! 
There’s more to the article if you can stomach it. She does cite Democrats who are working to mitigate the damage, IMHO without much hope of success.
The USA may never recover internationally from trump 2.0. I’m 77 and if it ever happens, it won’t be in my lifetime.
* One time in one of her posts, in referring to something about the Supreme Court, she did say, “That’s just bonkers!” which I found gratifying. Like hearing your high school principal, a nun, shout out the F-word, as though she just couldn’t hold it in anymore.
