If you are going to have any type of logical system based on truth values then when you encounter an error, you do not proceed until the problem is fixed least you accumulate more errors and target the wrong processes as being faulty.
This is what happened in Israel. There was a false flag by the Israelis and everyone went on processing information based on false information, and now we are discussing further processes in the chain of errors like "you were warned to evacuate the hospital, it is not our fault that you were bombed in it" or "we have the right to shut off your utilities and block your food and medicine".
We shouldn't be having these false conversations until we address things like: How come Israel can bomb small movements entering Syria which is hundreds and hundreds of miles away from their border yet couldn't see 1500 men and paragliders breaching their own border with weapons? Why didn't Israel take Egypt's warning as credible?
