You ignored the other, more meaningful indicator. Egypt did not have, nor ever will have, a ship with a silhouette anything like the Liberty. Furthermore, the Israeli had been notified in advance that the vessel would be present. The case has been fully documented in the public domain. It has been covered up by our government and the media. The attack was deliberate, and the Israeli knew the ship was American. You aught to research the topic, as you would find their reasons interesting. It was a matter of breaking Israeli codes and then broadcasting their intentions in the clear. From the Israeli standpoint, the US ship was breaching their security and divulging battlefield tactics to the enemy.
If this is true, then we were, indeed, cruisin' for a bruisin' by stickin' our nose where it don't belong.
