If you had read Hannah Arendt’s work on totalitarian regimes (Origins of Totalitarianism) - focusing specifically on Nazi Germany and the USSR under Stalin - you would never think this. As she says, and I am paraphrasing here, the consequence of people always lying to you isn’t that you stop believing everything but rather that you end up capable of believing anything.

And I’m pretty sure that effect is on full display already.

Israel doesn’t give two shits about the hostages beyond their propaganda value. That much has been obvious since before day one to anyone willing to actually believe their eyes and ears.
