The problem is that China does not want to become the US, they want to become colonial great Britain or France. The goal is classic mercantilism-all raw material have to go through them to become a product. It's barely disgused Manchester allover. The US by comparison has been quite dedicated to free trade. They abandoned there own production base, imported more culture then they exported and overall been quite frien…
On the other hand the 1st Gulf War was unavoidable, and overall with the exception of the 2nd Gulf War over the last 40 years they've more or less tried to do the right thing. Today it's widely recognised across parties in the US that 2GW was a mistake. Still, since WW2 they've sunk vast resources into guaranteeing Western European security, and spent Trillions guaranteeing global freedom of navigation that's benefited everybody.
They've been aggressive economically, true, but that's a whole massive deal better than being aggressive militarily and overall global trade in the last 70 years has had incredible benefits. Global poverty has collapsed to a tiny fraction of what it was, the middle class has risen from about 5% to about 60% of the world population, life expectancy rates have soared. Death rates from war have collapsed. The stats on that are up on the last decade it's still historically low. The majority of this happened after the collapse of the Soviet Union.
What Russia and China want to do is take the world back to a cold war situation of vying spheres of geographic influence. What the US wants to do is get out of the world police business while maintaining a peaceful global order conducive to business. So we have Russia and China flexing their territorial military muscles, while the US builds networks of alliances such as an expanded NATO, AUKUS, the Quad and such to better share the load.
I say alliances, but for the latter US strategy to succeed it eventually needs to include nations that are not traditional US allies. India, Brazil, Indonesia, South Africa, even places like Vietnam. These will or may never align with the US and Europe the way the US and Europe do, so such relationships will have to be transactional in nature. Partnerships rather than true alliances, based on common interests around eliminating the scope for military expansionism that favours big regional military hegemons.
So sure, a lot of past mistakes for sure, but the question for us now is where does the world go from here?
