I get that america is failing in it's duty to suppress the rise of fascists but did the rest of the world just put all its eggs in the america basket?

Yes, but also no. America has put a lot of work into breaking every other basket.

Well, South American countries made multiple attempts to put their eggs somewhere else and then found their eggs suspiciously smashed and their chicken appeared to have been replaced by a fascist dictator in the morning and when they asked what happened to the eggs they were put in a plane and quietly dropped over the ocean.

So there was that reason.

Yeah, it all built out of WW2. After WW2 pretty much all of Europe was in shambles. Most major cities had been bombed at least once, many far more than that. Infrastructure all across the continent was destroyed. The industrial capacity was destroyed. Armies had marched, pillaged, and destroyed first out of Germany across Europe, then back across Europe into Germany. The US was uniquely positioned as the only world power that didn't suffer massive economic devastation from the war. In fact, due to stuff like the lend-lease act and massive industrial mobilization for the war effort, the US was experiencing a massive economic boom while Europe and east Asia were in a depression.

But in the aftermath of the war the Cold War set in. The USSR and Allied powers (led by the US) drew lines in the sand and established their areas of influence. The US instituted the Marshall Plan in Europe which essentially just shotgunned money at western Europe to rebuild as much as possible as quickly as possible. This had a massive positive economic impact on western Europe, but it also ensured that so much of Europe would be dependent on American products and companies. If your rebuilt power grid was made with American parts, then anything new would have to be compatible with that, ensuring your country is a long-term customer of American products. At the same time, the US and western Europe created NATO as a military pact against the Soviet Union, which further strengthened the western alliance. Again, with the US as the only major western power with a larger and more powerful army after the war than before, the US took the leading role in NATO.

Another major factor that most people tend to overlook was the Bretton Woods Agreement in 1944. This was an effort to stabilize the global economy and monetary system after WW2. It said that the US would readopt the gold standard (we had abandoned it during the war, and would later permanently abandon it in the early 70s), then every other western-aligned country would use the US dollar as the basis for their currency. Think of it like a gold-standard, but instead of gold, they used US dollars. This gave the US enormous economic influence because everybody needed US dollars to maintain their economies, and the only way to get them was to do business with the US.

This created the conditions that the US expanded and exploited over the second half of the 20th century to cement ourselves as the dominant western world power. Through colonialism and Cold War dynamics, the US and USSR forced most of the global south to pick a side, and often forced regime change when they didn't like the choice countries made.

Then the Soviet Union fell and the US was the only global superpower left remaining. Over the 90s and early 00s a lot of formerly Soviet-aligned countries hitched their wagons to the US since it was the only game left in town.

So, yes, much of the rest of the world put their eggs in the America basket, but it wasn't recently, it didn't happen all at once, and, at the time at least, there were other factors that went into those decisions.

America demanded the role. America took the role and hoarded it.

Yes, at least for the Europeans that is very much the case. The Germans, for instance, were always morally appalled by the more overtly violent aspects of US Imperialism, but were perfectly happy to hide under their coattails and let them do the dirty work. The deal was that Europe world accept US hegemony in exchange for military protection. Nobody could ever imagine that the US would just rip up that deal because it will definitely hurt them more than everybody else.

I thought nobody wanted to give us eggs... 🤔

Its duty?!

The US has no mandate to meddle in international affairs, any more than a bully in grade school has a duty to stop smaller bullies from picking on their own victims.

The US has never been an international savior, it's the only country in the world to have dropped nuclear bombs on civilians.

After the 20th Century it became clear that war could spread anywhere at any moment and destroy vast swaths of people and nature indiscriminately.

The world had no choice but to ally with really big baskets. The USA was the most obvious choice given their lack of hostile landgrabs unlike China and Russia.

did the rest of the world just put all its eggs in the america basket?

No, you don't throw your eggs into a basket when the basket is foo far away.

It's quite the other way round. Imagine the North American continent drifting away from all other continents at the same time, and at an increasing speed.

This hasn't been caused by the orange problem. It was observable several years earlier. But when they decided to afford their orange problem for the first time, it increased the speed significantly. And now it is increasing again, and both speed and acceleration increase.
