End of the day Rubio and co who think they are entitled to chose governments in americas at will , need couple more million Venezuelan migrants ,as a result of in this case Trumps failed policies, probably Bolton's policies but Trump bought it hook line and sinker when Bolton sold him the idea to steal their oil , and US ended with millions of Venezuelan migrants and no oil
If you take a honest look most mayor Oil producers are effectively socialist -Communist dictatorships are relatively poorly managed but boon in income offsets the corruption and mismanagment , citizens are pulling rent of have no show jobs, most of them also run massive imported foreign labor force to do actual work, Even most effectively managed Norway is a socialist with foreign workers keeping the lights running.
Venezuela is just most effectively sanctioned,Iran flowing close second but geography means Iran and Russia are much harder to sanction than venezuela and unlike venezuela they are much more self-sufficient in terms of industry,agriculture etc.
I remember when traveling south americas cca 15y ago ,venezuela was funding projects in so many south american countires , while not building much industrial capacity domesticaly, was kinda like gulf states prior Gulf war , pre diversification drive that is why sanctions bit so hard.
