Trump's former advisor Sebastian Gorka said: "salt the earth with the people who did it" when discussing the war.

Speaking to GB News he said: "This idea of proportionality is asinine. When you're killing children and raping women after you killed them, then you must salt the earth with the ashes of those who did it.

"There will be collateral damage because that's the nation of war, since man first picked up a rock and hit his enemy in the head with it. So we need to be realistic.

"War is the history of mankind and we need people who will prevent it by being determined in the protection of their nation. And Israel has every right to make sure this never happens again to them."
