> are you seriously saying Maduro had Hitler-like potential to ignite global war if we didn't stop him?

No, and in fact the comparison to Hitler felt out of place. I'm simply saying that it isn't as black and white that one should NEVER remove a head of state.

What I will concede is that catch 22 of not knowing how the future will play out, so how COULD you confidently and with wide agreement intervene BEFORE someone commits atrocities.

Well, while comparing Maduro and Hitler is a bit excessive, he has successfully driven out like 8 million people from Venezuela. That's something.
