Why so many Americans haven’t heard about the USS Liberty

Al Jazeera's Ava Warriner discusses the 1967 attack on the USS Liberty, a U.S. Navy technical research ship. The attack, which occurred on June 8, 1967, resulted in significant casualties and damage to the vessel. Warriner explains the events of that day and alleges that a subsequent cover-up followed the incident. The article suggests that this alleged cover-up may be a reason why many Americans remain unaware of the attack.
