I would further note that, if one is looking for something to dislike about the embargoes, being a blockade isn't necessary. In particular, (classical) liberals should be disturbed by countries forcing private shippers to participate in "their" country's embargo. E.g., would the US attempt to stop and American company from trading with Cuba?
