Israel screwed up, big time. Lots of people believe it was intentional, including me.
The reasons remain unknown. We do not know the reason Israel attacked, nor do we know why our own government chose to let them get away with it.
A lot has happened since then, and it is not relevant to the current situation at all.
There have been nearly 35 years for either government to punish the guilty parties, or at least to conduct an honest investigation. That has not been done. That makes it relevant today, in my book.
