To the best of my knowledge, no Jewish leader was party to this monstrosity. It is the fruition of a campaign by Islamic leaders to bring Christianity to heel, and the Jews will be dealt with subsequently, when Christianity no longer defends them.
Made possible by the evil collusion of the apostate pope.
“the Jews will be dealt with subsequently, when Christianity no longer defends them”
And if you look at the Muslim end times prophecies, they then plan on killing the Christians once they are done with the Jews.
