I thought that was pretty much the point. It's not a tennis match. Ironically, the more lop-sided the killing, the QUICKER IT ENDS! If the Japanese had thought they could hold out during a land invasion of Japan in 1945, there is no telling how many more hundreds of thousands would have died on both sides. Hiroshima and Nagasaki raised the price of war to a level Japan could not pay. When you mow 'em down like mowing a yard of grass, they quit.
In war, the cost for one side has to be too high to continue.
But for each American death, literally hundreds of Iraqis die.
Actually, I think it is about 1000:1.
