Could we move away from a political argument that can only shut this thread down and back to the politics of Sol-1.
I agree that many American agents of Infinity would be attracted to Sol-1. And not just Homeline Americans. Picture an American where there was a WWIII and America lost. Or any parallel where America just got to start to show its stuff and got nipped in the bud. Or just an America where freedom failed and was crushed. An America going to the stars in glory would be profoundly seductive.
Add into that, the fact that in this scenario many other nations would be having golden ages. A stable prosperous democratic Iran would likely be going through a Golden Age culturally. An Iranian culture is attractive and magnificent at its best. Iran might be taking the West along on its new Gold Age.
India would be booming in this world too. If you've ever heard
Bally Sagoo then you might have some idea of what Sol-1's pop music might sound like.
Now, there would be those opposed to this new American Century. Terrorism would be a threat if only because many dreams would be obviously dying as they failed to compete for dreamers. Certainly dictators and oligarchs would have no love of this new world. As more people became aware of what was possible, if they lived in a democracy, neither oligarchs nor dictators could rest easily. They'd be quick to fund disruptions. Cultures that reject change would find themselves stretched to the breaking point and might fall violently apart.
These seem to me to be better elements to explore.
