Where are you getting this 1/5 number? According to the Gaza Health Ministry casualties are somewhere around 60K.

Are you claiming that the Gaza Health Ministry is lying?

Also why would you assume Israel is going to stop the war if Hamas doesn’t release the hostages? Our goal is to end the war isn’t it? How do you imagine the war ending while Hamas continues holding hostages?

Hamas massacred villages. I think a it takes a real rube to believe a group that massacres entire villages would never lie to you.
