There's definitely something more happening. Don't think some of those big bad corps are going to let their nationalized assets be forgotten. The big news here is that Obama was actually able to get this through. Which makes it more obvious something else is happening.
I doubt we'll see much redress for that, but certainly the Floridian cubans include reparation like demands, of course in this case the adage of "asking blood from a stone" surely fits...
There is certainly something more happening - while Latin America has been out front for decades on this including Cuba in more and more of their regional international institutions we have seen slow thaw in American political attitudes. Even with Democrats fully turned around on this from some decades ago the remaining issue was the Republicans still having such strong ideological committment to the embargo and having some political incentives to be that way given the importance of Florida to the election cycle in presidential years.
The corporate angle here is actually one of the lesser-weighted factors in driving to this day.
So are you actually saying this in this instance, American foreign policy is not driven by economics?
