The Submarines of October: U.S. and Soviet Naval Encounters During the Cuban Missile Crisis
You don't know what you're talking about.
Did the USSR ships THREATEN the naval blockade by getting into theie face? Even a 6th grader knows the missles were tansported by ships.
Again you are missing the main point...Cuba/USSR whoever BACKED down. Zelensky/Biden/NATO have nor backed down. That is the MAIN POINT. Stop arguing liek a 6th grader.
