I would think a reasonably intelligent individual would be able to deduce what my answers would be to your questions, which I didn't think even warranted a response, as they were non-serious.
But, here ...
"OK"? Define "OK." "OK" meaning it's preferred? No. "OK" as in not being OK requires immediate military intervention? Yes. It is what it is. Countries we don't like will have allies, countries they do business with, etc. It happens. We don't destroy any country that talks to a country we don't like.
This is a silly "what if" because there's no indication anything like this was on the table, even in the longer term. But, just for poops and giggles, I'd say, it depends on what else is happening and what actually led up to it. Far too speculative a hypothetical situation to give specific actions and reactions. We can't just go around taking over every country that might eventually have Chinese missiles in it. We may as well just take over every country. Wouldn't that be just peachy keen?
I already addressed the overly speculative nature of this line of questioning, so there's not much to say here ... I'm going to assume we would have done things - diplomatically, economically, militarily - before that happened that would shed better light on next steps there. But, again, this is silly ... from where we're at, to then jump to "Chinese missiles in Venezuela." You can justify all sorts of evil with that line of thinking. As someone else said ... this is Putin-level dictator crap ... probably worse, since there's such a small connection/possibility here. It's insane that this is happening at the whim of an American president. More insane folks like you support it. Did you ever think you'd become a Nazi/fascist? Do you not realize that's what you are?
So, one country floating a balloon justifies taking over a completely separate country? What was the president supposed to do? You have no logical connections here, so it's impossible to speak on this, logically.
