The pilots even radioed in to have their orders restated several times because they knew it was a US ship. One of the torpedo boat captains also radioed in and said the ship they were ordered to attack didn't match the profile of the Egyptian ship they were told it was but rather looked like a US ship. None of that mattered.
Like all military organizations, what the people ordered to do the killing or provide "proof" to someone think about a situation and care about has nothing to do with what higher command orders them to do.
The Israelis "know" whatever it takes to further their agenda and it's been that way since day one of the State of Israel. I thought Trump would be just a smart about putting America First, but apparently not.
>>The Israelis knew which Egyptian air unit attacked the USS Liberty, too.
