Should read: Third possibility as well is Israel intercepted and misread a shore based communication from a covert operation and assumed LIBERTY was involved. The LIBERTY crew would not have picked up on it and would have been clueless.
I’m not seeing a whole lot to disprove the fog of war defense the Israelis put forth. Yes, they knew she was in the area, but so were a whole lot of unfriendlies. Mistakes were made on both sides.
