The kind of groups who fell for enemy bullshit were generally neolithics, very primitive, and very unlikely to survive. Most didn't.
Diodorus Siculus talks about how they were saved from dying of thirst in the desert by some mysterious force. Many historians, such as Josephus or Tacitus, attest to some version of this, either through offering donkeys as a sacrifice, or being guided by floating donkey heads.
These historians were mocking (rightfully) the jews, but the common idea is that they were saved by lesser beings, and not for free.
They were too low in their evolution to notice the strings attached to dealing with these entities, and by the time they likely realized the risks, the damage had already been done. Damage being that the jews can only continue to exist and survive through symbiosis with these parasites.
What options do they have, other than march towards their own demise and defeat, and perhaps get to enjoy some power in the meantime?
That being said, none of this forgives any of their actions, and all consequences incoming for them are deserved, and will be beautiful to see.
