OK, then forget the sermons; how 'bout this?

The USA, like all serious countries, seeks to defend and advance its interests. Those interests include the suppression of self-declared enemies like Cuba and Iran, or seeking regime change so they cease being self-declared enemies of the US.

The irony of your claim that the US is starving the Cuban people is that in fact, the US could go that far and it would actually end the enmity from Cuba. But they haven't and they won't. It would harm other interests, possibly engender enmity elsewhere, and outside of total war Americans don't play the game that dirty.

But if people widely believe that's what the US is doing anyway, and they're "doing the time" without having actually having "done the crime", then considering that actually doing it would end the enmity from Cuba, it starts to look awfully attractive to Just Do It. So claiming that they are, when they actually aren't, only makes it more likely that they will.

Anyway, given that both ex-communist states China and Russia have demanded economic reforms from the recalcitrant Cuban regime--which have not been forthcoming--and that food is not embargoed, I think the impoverishment and hunger of the Cuban people can't credibly be blamed on "el bloqueo".

Cuba now imports their sugar--from the US of all places! You really think that it's American policy starving Cubans?
