Every single time that there's some internal issue in Argentina, three magical syllables pop up: "Malvinas" (aka Falkland Islands). The goal is not the islands themselves, but to distract the population from that internal issue. It works: some mass idiocy/nationalism surfaces out of the blue, and people look to UK with angry and ineffective middle fingers instead of looking at the internal issue.
I think that USA is trying something like this, with those idiotic comments about Greenland, Gaza, Canada etc.; or at least, as part of the goal. If that's correct the "we'll buy California then" mockery won't help much, it's simply better to bombard the media with the ongoing USA internal issues. Like, dunno... trying to marginalise further groups that are already marginalised, by the removal of diversity, equity, and inclusion frameworks? Or perhaps that all those taxes are going to hurt United-Statian pockets way more than anyone else?
Just my two cents.
