Ah, but when it's the US it's fine. They're the champions of democracy, aren't they?
Not at all arguing that it somehow leads to justification for an illegal invasion.
In this specific case the claim comes down to assertions of a sham election. If this was indeed the case (with the lens of an international survey obviously the US view is suspect considering the attack), then the Venezuelan people themselves do not view him as a legitimate leader, which simplifies the situation.
I think my assumption that the legitimacy of a government rests in the eye of the beholder is pretty reasonable.
Step out of your American exceptionalist bubble for a second. How would you like if the inverse were true? There's some shady elections in US so Venezuela decides to throw bombs on Washington. How would you enjoy that?
It's really really difficult to paint this as inherently bad, it's hard to see how the conclusion here doesn't entirely depend on how you feel about the results of the previous Venezuelan elections.
