> My issue with your phrasing is the assertion that El Salvador is somehow a 1-year relationship or detention.
Nobody is going to hold prisoners from another country indefinitely for free.
Where there's money, there's some kind of agreement. Even if it's completely unspoken and unwritten (which I doubt either way).
If the money stops, so would their acceptance of droves of new deportees.
Not to mention that $6M for 300 people indefinitely is nowhere near enough... but for 1 year it certainly makes a lot more sense, I think that comes out to $20k/yr per person, which is cheaper than what it costs the US to do the same.
