There's this scene that lives rent-free in my head, with a character in the show The Diplomat saying "i still believe in international rules-based order". It's killing me lol. And it shows exactly the point of their jobs: cover-ups. Politely excusing horrible war crimes.
This is not just Trump. It's a long history of the US and other countries doing what they want, because who is going to stop them?
Just like West Wing, The Diplomat is a fantasy for liberals, and even then they can't make themselves look good.
Dozens of assassinations, kidnappings, regime changes, support for violent extreme-right groups... par for the course for the US. This won't stop until the US collapses.
