The guy you used is a notorious grifter in that regard. And he is the only one who is this crazy. But fine. Firnedly fire doesn't happen. It is all a conspiracy. Friendly fire is fake news.

As for antisemties this is one of their holy grails. To try and paint Israel as evil.

In May 1968, the Israeli government paid US$3.32 million (equivalent to US$24.7 million in 2020) to the U.S. government in compensation for the families of the 34 men killed in the attack. In March 1969, Israel paid a further $3.57 million ($25.2 million in 2020) to the men who had been wounded. In December 1980, it agreed to pay $6 million ($18.8 million in 2020) as the final settlement for material damage to Liberty itself plus 13 years of interest.[9]

The amount of money paid in reparation is huge. He must have ran out of money to be gifting like he is.
