Kimberly Guilfoyle, the US ambassador to Greece, told a room full of Greek and US officials in Athens that America could topple any government it wants, including Greece's. This came up during a private dinner discussing Romania's government collapse. Greece's energy minister Stavros Papastavrou had to push back, reminding her that Greek voters elected their government. The comment is breathtaking in its nakedness. An official US diplomat saying the quiet part out loud: regime change is a tool America uses when it feels like it, democracy be damned. The fact that it happened in front of Greek officials means it wasn't a slip, it was a message.
