"Israeli authorities subsequently apologized for the incident, but few in Washington could believe that the ship had not been identified as an American naval vessel. Later, an interim intelligence memorandum concluded the attack was a mistake and not made in malice against the U.S. . . .

I had no role in the board of inquiry that followed, or the board's finding that there could be no doubt that the Israelis knew exactly what they were doing in attacking the Liberty. I have yet to understand why it was felt necessary to attack this ship or who ordered the attack."
