By that logic, NATO is already in the waters off Venuzuala and it's blowing up civilian ships.

I think you need to learn what NATO is. You definitely need to understand that nations of NATO act independently or within other alliances every day, not as part of NATO.

NATO had no stance on the Houthis; they have no stance on Venuzuala... These things have nothing to do with NATO. They're just busy doing their thing, bolstering Eastern European borders against Russian drones—which is exactly what they exist for.
