Within Geopolitical commentaries that I used to watch, A famous quote by Henry Kissinger is often repeated.

"to be an enemy of america can be dangerous, but to be a friend is fatal"

So yeah, America has never been trustworthy in a way but it still had its upsides and it still had some laws and checks and people still believed in some aspects of the American dream somewhat, Not anymore.

But now?,it has never been this less trustworthy either in a way to the whole world.
