Haha, well, most countries US spents "US aid" were destroyed by US before or had "regime change" by US before or were economical pressured by US before (e.g. sanctions) so that they were unable to develop themself their needs. Whereas "US aid" is also (and in the sum the most) military aid to e.g. Israel ect. or Proxy fighting groups ect.
Technological the US is on the decline. The technological advantage, coming from the theft of german patents and researches after ww2, only holded on to the 70s, then slows down even the US still theft technologies from other countries. Today the US is only second, third or lower in most technologies.
And what art? Pedophil Disney channel? Woke bullshit? Sick Hollywood films? Lol!
And what sience? Most "siencific succsess" in US is made by foreign scientists working there.
What US is good in is destroy smaller countries, do regime changes and pressure the "friends" in "the West" to support with sanctions for to destroy other countries economic. And that all for to delay its own crash, suck other countries life out to delay. But even that is on the decline cause the perferted world dollar system, what let the US survived till now by making hughe dept, is on the decline.
