It's fascinating to watch. In MMA terms, Israel is a highly-skilled Middleweight, while Iran is a Heavyweight with less skill but more brute force.
Israel is landing more strikes and doing more damage. But Iran has landed a few heavy shots and, because of the size difference, can soak up more punishment. Israel's chin and gas tank are being tested.
Of course, very soon this will change from UFC to WWE: America will go Full Undertaker, climb into the ring and smash Iran over the head with a steel chair.
