Israel is strong enough to commit genocide in Gaza and does not want to. Hamas is too weak to commit genocide against Israel and wants to desperately. And Hamas did commit mass murder, targeted civilians for rape, recorded and celebrated the personal killing of children in barbaric ways, and then ran back into tunnels to hide from a real army.
Those three sentences contain the entire moral reality of this conflict. Everything Tucker Carlson said is a lie measured against them.

If Netanyahu meant literal extermination of every man, woman, child, and infant in Gaza, and the Israeli military has the demonstrated capacity to achieve that in roughly two weeks, then the population of Gaza declining by less than one percent over 31 months means one of exactly two things: either Netanyahu did not mean what Tucker says he meant, or the Israeli military is the most catastrophically incompetent extermination force in the history of organized violence.
Tucker wants Israel to be powerful enough to control the United States Congress and bankroll its own genocide with American tax dollars, and simultaneously incompetent enough to attempt the extermination of two million people and kill less than one percent of them over nearly three years. Those are not two positions a serious person holds at the same time. They are two incompatible antisemitic tropes wearing the same coat.
