Honestly, I think this is an existential moment for the US. The US is a country I love, and it's a people I admire (and married into). But that's not to say it's perfect, and this is a moment when reality impedes of accept truths and beliefs. There is an embedded idea that the free world can only exist with the US, and that any assistance or funding the US gives is charity. This has never been true. Aid/grants/loans call it what you want, but they are NEVER given without for reasons, purely, of charity.
The current situation will have ramifications few have imagined. I do feel that many Americans (and I don't mean to insult anyone here) simply don't get it. The damage being done right now will be lasting, and it's not to the benefit of the US. This is really sad, imo. I know members of this site are sensitive to criticism of US policies, so I won't go further. I'll just say that what I'm seeing now is something that hasn't existed since pre-WW2.
