There's a big component to all of this that people are missing, and I know the flag-waving Americans may not like to hear it, but here goes.
America has a big army, yes, but strategically in war, you guys aren't that great. You assume, through past conflict fought, that bigger is better; after all it worked for Russia with their advantage of numbers vs the Nazis, and it worked in Japan with the biggest bombs. Today though, that American view of the battlefield is out-dated, and has been since Afghanistan.
In Afghanistan, the European nations (headed by Britain) gave specific instructions to the Americans along the lines of "Do not just flatten everything and murder everyone, or your enemy will become more like by the people and thus the people will turn insurgents against you". That's why the Hearts and Minds campaign was thought up.
The UK and Europe had a deal with the Americans; it was their war, they take the credit but follow the advice of the Europeans strategically. Sometimes America listened, sometimes it didn't.
When America gave the middle finger to its allies and went guns ablazin cause "fuck you, murrica" we ended up with the abysmally withdrawal from Kandahar.
The point of all of this is that America attempting to run a war by itself, using superior numbers and 'superior' tech, would get their shit pushed in by a more strategically capable army/country. It wouldn't be the first time this has happened, just read into how napoleon galumphed around Europe and made a mockery of the biggest standing armies on the continent.
I believe we are seeing a role reversal in Ukriane, where Europe supplies the equipment (I know America are as well) and America take tactical control. I think that's why we are seeing such a shit show.
This may sound like I am slagging America off, I am not. I'm just relaying some information based on past, personal experience.
Thanks for reading this long post I typed up while sat on a train
