The only thing that is in danger is the Argentinians. Their military is probably in worse shape than the last time they tried to invade, and the British have gotten a huge amount of new gear since then.
I suspect the USA would also be much more willing to get involved this time around, too.
Definitely, but the difference is that the prior administrations were extremely corrupt. Basically all the histrionics they say on fox news about the US is actually literally true in Argentina.
