And if you scratch the surface, you will quickly realise that their apology is bullshit.
Israel wanted the US involved and conducted a false flag operation:
“Some intelligence and military officials dispute Israel's explanation.[79] Dean Rusk, U.S. Secretary of State at the time of the incident, wrote: I was never satisfied with the Israeli explanation. Their sustained attack to disable and sink Liberty precluded an assault by accident or some trigger-happy local commander. Through diplomatic channels we refused to accept their explanations. I didn't believe them then, and I don't believe them to this day. The attack was outrageous.[80]”
