It's not a fantasy. They are living it.
The US is not a weak country, its not poor in terms of capital or resources, it is not small or isolated, and it is not incapable of innovation. Far from it, it's number two in most of these areas, number 1 at least in terms of capital. It is also a deeply unequal country that is unable to face down even one of its contradictions.
Latin America is a truly awesome place if you're already rich. And so is the USA.
The latest from Justin Podur talked in depth about one aspect of the Syrian War that IMO has become a bit of an elephant in the room. This is one war where sanctions played an important role, albeit with massive caveats.
There was a civil war that ruined the country, and then a part of it was occupied. That part was permitted some rebuilding and was supplied by the occupying force. Either financially (Americans buying the SDF's oil in the northeast) or directly (Turks sending their oligopolies to rebuild and supply the local economies in Idlib and Afrin). The portion of the country that remained under control of the central government more or less failed to rebuild - wether that's an indictment of Assad's government, Russia's and Iran's financial werewithal, the power of the sanctions themselves, or all of the above is up for discussion.
The truly bleak statement from Justin is that while the sanctions architecture might create a real demand for acquiescence, the moment the country bends the knee slightly it doesn't get rewarded for it. Western policy seems all stick, no carrot. Assad is gone. Yet Syria went from being bombed 3 times a week by the Israelis to 300 times in 3 days. The entire security infrastructure of the country is just gone. And still the Europeans and Americans are dithering on wether they'll even remove sanctions imposed on a new regime which, by and large, is giving them everything they ever asked for and then some.
So in my view this is a cautionary tale to the likes of Venezuela and Cuba. Juan Guaidó could have taken over the former and turned PDVSA into a Chevron subsidiary. Something tells me the Americans would still never forgive these countries for mildly inconveniencing them.
