But as always the true power in a relationship is from the subordinate party, they can always say "no"; i.e. take their ball and go home. Authority comes from submission. Maybe this is why Cuba is still hounded even worse than the USSR ever was, they refused to play along.
In the end sovereign relations is little different from playground antics; pleading your case from the stance of rationality and/or fairness doesn't get you very far, only once someone is seriously hurt do things change (sometimes not ever then; Stubenville anyone?).
