a. Sure, if we're disingenuously ignoring the meanings and implications of words today for some reason.
b. For the first part of this question, here's a response I made elsewhere that addresses it:
"The article doesn’t address that, so I’d be speculating, but if I had to guess, I’d say either:
- US authorities determined that Panama had some sort of culpability for the migrants entering the US - maybe they were lax in their policing of the Darien Gap, for example
or, also quite likely given how much of a petty dick Trump is:
- Trump forced Panama specifically to take them as a show of power related to his threat to steal the Panama Canal."
For the second part of your b. point, I don't see a reason that this is a bad thing for Panama to do, even if it sucks that they're the ones having to do it. This isn't a concentration camp - it's a temporary camp until the migrants can be repatriated.
I'm not sure what you mean by "legitimately returned"? Do you mean that Panama can't be sure of their place of origin?
I fully agree that the detainment camps that Trump inherited from Obama were inhumane, but in my opinion a lot of that was due to the unreasonably long amount of time people were forced to spend in them. Most of those conditions (obviously not refusing to provide soap, turn the lights off, etc. - that was just intentional cruelty) are reasonable for a few weeks or so, as a temporary stop-gap, but after months of detainment it definitely becomes inhumane.
We don't have any evidence that the Panamanian camps are doing any of those things though, or why Panama would want to treat them like that.
If anything, this seems like an improvement.
