What was antisemitic was saying that Israel deliberately allowed the abduction and mass murder of their own people, in order to give them an excuse to invade Gaza.
I will never believe that - their security has always been unbelievably tight and vigilant - it has needed to be. I well remember the case of some poor gullible girl who was led to believe that some vile man was in love with her and wanted to marry her. He told her they’d get married in Israel and gave her a suitcase to take - with her wedding dress in. He would meet her there, and told her to book the El Al flight on her own.
She was identified at once as potentially suspect as soon as she went to book the flight - she just seemed ‘wrong’.
The much more serious checks came when she tried to check in for the flight. Of course the suitcase contained a bomb, intended to blow the poor girl up, along with everyone else on that plane.
