Is the meaningful thing you are trying to get across here something like: "everyone is saying USA is doing something really bad, but in fact they are not"?

Or maybe more: "ok USA might have it a little out for Cuba, but remember, everyone else hates them too, otherwise they would be trading with them"?

The meaningful thing is to understand the difference between a blockade and an embargo.

When people say that the US is blockading Cuba I'm not sure if they are genuinely misinformed and think that the US Navy and Coast Guard are physically apprehending any ships trying to dock in Cuba, or if they are just ignorant about the difference between a blockade and an embargo.
