Eh.  The Zionist entity launched air and ground surprise attacks and immediately claimed Egypt had attacked THEM.  The Zionists subsequently changed their story from "Egypt attacked first" to "we did a 'preemptive' strike."  The attempted sinking of the USS Liberty and murder of her crew was to prevent them learning that IDF forces were already mobilized to attack the Golan Heights (which happened the next day), and/or the IDF mass-murder of 1,000 Egyptian POWs while the Liberty was only 13 miles away.

Sorry, not gonna accept any defense of these mass-murderers to accommodate an apparently widely-held misconception that today's atheist apartheid state occupying Palestine has anything to do with biblical Israel.
