This is the Ron Paul position and its a solid one.
The non-intervention principle applies if you are not actively suffering intervention.
The flaw however, is that applying non-intervention in this instance, is choosing to ignore the real, direct hurt currently endured by non-actors (LATAM + US citizens) from the policies of Maduro.
I do concede that whatever follows Maduro, may be worse.
If I'm getting poked by a neighbor for years and i finally punch back, punching is a valid response. If the neighbor then comes back later and shoots me with a gun, it doesn't mean that my self-defense act was invalid.
It isn't necessarily just a non-interventionist stance. Someone could be taking this position in this situation because they're highly skeptical that the Americans involved in this have the ability or desire to proceed in a way that will result in a minimum of casualities or in a way that will bring about real democractic change to the region.
People want an Eisenhower doing these kinds of things, not whoever is doing currently doing it.
I've met Ron Paul.
You, sir, are no Ron Paul.
Invading and kidnapping the leader of a sovreign nation sounds rather illegal to me.
