> Really? I thought the US just arrested Maduro. To me, that seems like something that would matter.
You can't arrest a foreign head of state in a country where you have no jurisdiction. You can only kidnap them, as a rogue state.
Do you think Iran should be able to arrest Trump because they don't consider him legitimate?
International law isn't "I don't like you, so I will 'arrest' you". It's rules that all countries are bound by and that the US is breaking - making themselves a rogue state on the same level as North Korea.
> Can you actually try to explain why? Can you explain why a reasonable person looking at this from the outside should arrive at the conclusion that "Maduro was the legitimate government"?
Because he led Venezuela, that's what makes him the government of Venezuela. Any judgement on legitimacy is reserved to the Venezuelan people, not far-right oligarchs (who the US government considers the "legitimate government" since they'll make for nice puppets as they rob the place), not foreign dictators like Trump.
