The only success stories America has with nation-building are Japan, (West) Germany, and South Korea, and West Germany was a joint-effort between America, the UK, and France.
All their other attempts, not including the utter clusterfucks in South and Central America (for various reasons)? Welp, let's see...
Iraq and Afghanistan are still shitholes no matter how many lives and dollars were thrown at them over the course of twenty plus years, and the latter is now back under the control of the Taliban (which quickly reversed almost everything the Americans tried to impose on Afghani culture, such as feminism and basic rights for women). Womp womp.
Libya and Syria are still being fought over by at least four different factions in each country, and no attempts at nation-building could be attempted because of other countries' interests (such as Russia) in both countries. Womp womp womp.
South Vietnam still fell, no matter how much America propped it up with funding, troops, and training. It's now just Vietnam, which is technically communist. Technically. Womp womp womp womp.
Now, if we look at things militarily? Yeah, not a good track record either -- ever since its founding, the US has outright lost, claimed what are basically pyrrhic victories at best, or came in late to the party while other nations did the initial heavy-lifting (such as in WW1 and WW2, though the Second World War couldn't have been won without American involvement) in various wars.
The only real victories America can claim are their initial War of Independence, the Mexican-American War, (jointly) the Second World War (and even then they only really became involved because Imperial Japan got desperate and thought picking a fight with a sleeping giant was a good idea), the Korean War (which was primarily American troops), and the Cold War (ideological, but honestly with how things are going now, it's looking to be more a pyrrhic victory than an outright victory even there).
Trying to invade and annex British Canada? The Red Coats, outnumbered, sent the American militia mauled and broken back to Washington DC.
The American Civil War? That was basically a complete self-own, as all the casualties, Confederate or Union, were American. You were killing your own people!
Cuba and the Philippines are their own messes/can of worms.
WW1? Came in too late to make any real difference, and the outcome of the War was pretty much set before the first official American troops arrived in Europe.
Vietnam was an outright failure.
Afghanistan and Iraq? Outright failures on par with Vietnam. Hell, Biden's retreat mirrored the Fall of Saigon, right down to Americans and other nationalities scrambling to get onto choppers.
So, yeah. Despite all the troops, the technology, the training, and the manpower? America has an awful track record. Most of their successes came from the early 19th to mid-20th centuries.
Just cause.
Grenada.
Yugoslavia.
03 invasion.
Outside of 1812, and even then we beat the brits back in New Orleans.
Was a draw.
Outside of 1812, the military has basically been unstoppable in its escapades.
We beat back a combined VC and NVA offensive, the Tet Offensive..
In Iraq and A-stan we faced hard battles but we often and AFAIK won't near os not every battle.
So the military didn't lose.
The politics lost
