I don't really know what to say at this point.
As far as the legality of what we did, I don't see a problem with it (at least I don't think so). The United States should be able to steamroll some random guy in Grenada or Venezuela if we feel like he's a bad actor. International law and the ICC is a bad joke and shouldn't constrain our behavior. Domestically, the War Powers resolution should allow the executive to do something like this.
The problem is, why are we doing this? And who is "we"? I have never seen convincing evidence that removing Maduro will reduce the flow of drugs into the US, or that it will remove communism from the country. As far as the oil, if Exxon Mobil or whoever is able to drill in Venezuelan oilfields now, that's great for them, but how does it benefit the rest of us? For some reason, I don't think Americans will get anything out of this.
The drug angle is especially stupid because Trump just pardoned another South American head of state (Juan Hernandez) who is on tape wanting to "shove cocaine up the noses of gringos."
The only country that tangibly benefits, at this point, is Israel, given that Venezuela has been a known and acknowledged thorn in their side for years. It's no surprise that the next presidential hopeful Maria Machado will not shut up about how many things she's ready to do for them.
Some people are alleging that China and Russia were establishing a foothold in our backyard with Venezuela. They do indeed supply some oil to China (2-5% of China's supply) but I haven't heard of any other involvement, certainly nothing substantial enough to warrant regime change.
I also have a problem with the example this is setting globally. We are going to charge a foreign head of state with possession of machine guns? So when Germany brings an American citizen up on charges for violating their hate speech laws are we going to pretend we're better than that? Are we still going to pretend that Russia invading Ukraine was unjustified?
If Maduro was repeatedly aggressing on the US and uniting himself with China/Russia, I don't think I have a problem with this. But I just don't see it.
Glen Beck actually nailed the Geo-Political game at play here (which is a fucking wild sentence to say): https://xcancel.com/glennbeck/status/2008289807374385386#m
Same with Firas Modad, but Geo-Politics is his job: https://www.youtube.com/watch?v=AhuqlU7rzA4
This effort is about out-maneuvering China and beginning to secure the Americas from Chinese influence. China out-maneuvered us badly by vassalizing Canada, Mexico, New Zealand, Australia, and damn near the UK, and even risking our nuclear naval deterrence with the UK selling an island to a Chinese proxy. That's nothing to say how undermined we've been in America.
Meanwhile with Venezuela and Iran in extremely vulnerable spots; China is risking an economic collapse with high energy prices, can not foment an invasion of Taiwan, it can not maintain BRICS maneuvers, and they just lost a monopoly on rare earth minerals. I suspect a new round of trade negotiations on China will probably start relatively soon. Meanwhile, Guyana (an American vassal state) is secure, and Leftist influence in Brazil and Argentina is going to be less well armed and weakened.
