The USS Liberty incident is so often used as a boogeyman to make Israel seem overtly malicious to the USA. Often forgotten is that the day before the incident, the Israeli air force accidentally bombed one of their own infantry columns.
Any state based on racism and supremacist ideology and found and controlled by persons who were explicitly terrorists (likud descends directly from irgun etc) is a threat to not just the US but all of human kind...
But you can't really say that about Israel because they'll use the default antisemitism attack, alongside various dogwhistles to encourage harassment, until you are silenced.
