Does the US even want Argentina to do this? Argentina is such a black hole economically and with so many different creditors already, that trying to integrate Argentina any more into the American Orbit risks destabilizing the whole thing.
There’s a huge movement in the direction of dedollarisation in the global South. The state department would definitely be happy to see a country go into the other direction. Plus there’s a whole bunch of state assets that are probably going to go on a fire sale, so Argentina can look forward to being effectively owned by Blackrock for the next century or so.
