Where is “it’s not a blockade if the ships don’t have papers” set out in international law?

> Yes it was a blockade!

Funny. Kennedy tried your exact denialist tactic - they called it a quarantine.

History, of course, isn’t fooled.

> The US military deployed its forces with orders to seize Soviet ships bound for Cuba (though they turned away before any ships were actually boarded).

And you are somehow privy to the Coast Guard’s orders in the Ocean Mariner case? How do you know what would have happened if they made for Cuba?
