Why would the government of Israel create a group like Hamas in the first place, and continue to manage it throughout its existence?
To keep the Palestinian leadership of Gaza and the West Bank rivals and prevent them from joining forces in their quest for a separate and unified Palestinian state.
I have an Egyptian friend that is utterly convinced of that premise. The utter illogic does not matter, it’s what he has been told his entire life.
Look at those who were lied to about masking/vaccines/multiple shots, and their complete conviction that “the anti-vaxxers” were the ones misled. This was only over a very short term of months, though it was from EVERY common media source.
Now expand that to one’s entire life experience.
Some folks are irredeemably misled, and there is NO way to release them from their mistaken perception.
