So Obama was going out of his way to signal to the Brits that he wasn't going to support them on this Falklands thing. He was going to be reflexively anticolonialist (as he always is - it's one of his constants) and be on the side of The People. Except the people want to be British, but who cares about the actual people when you can be for The People.
So Obama goes for the intentional diss and calls the islands "The Maldives."
Um, yeah, I think "The Malvinas" is the phrase you are looking for there, dude. The Maldives are elsewhere. If it was just a flyby comment, talking about the islands as part of some list or obscure example, it would be a small thing. It's the sort of error people make all the time, and it doesn't mean much. A slip.
But the choice of name was his entire point and he couldn't get it right. If you were having a live serious political discussion and made that error, your opponent would gently sneer and say "I think you mean The Malvinas," and you would be utterly humiliated in that conversation. You would be revealed as a poseur who did not actually know anything about the subject but had just picked up a few scraps and were trying to club people with them.
In everyday conversation it would be a big thing, but in foreign policy it's nothing? Seriously?
Obama is IQ 115 masquerading as 145. Now, 115, with proper humility and graciousness, might actually be a high enough number to be a very good president. I'd prefer up over 125, but beyond that, you don't get much value-added for each ten points, as you might in STEM studies. 115 is doable.
But not if you pretend you are something else, the smartest person in the room and above all those others. Then 115 is death.
