The US ambassador to Greece openly threatened to organize a coup if its government didn't do what Washington wanted.
US ambassador Kimberly Guilfoyle is a top Trump ally who was previously engaged to Donald Trump Jr.
Guilfoyle had a fight with Greece's energy minister, and she referenced the collapse of the Romanian government, saying:
“We can do that to any country we want. We can do that here”.

This is reminiscent of what was said by Elon Musk, the world's richest oligarch, following a US-backed coup against Bolivia's left-wing President Evo Morales in 2019:
"We will coup whoever we want! Deal with it".
