I literally just told you that the Soviets should have been taken out. This fact doesn't change the moral calculus of the strategic bombings against Germany and Japan. The fault was not doing the same to the USSR.
I understood what you wrote. The interesting part of this quote is apparently General Patton also realised they should not have been fighting against Germany in the first place. There are other quotes from him that indicate some regret of fighting against Germany instead of the Soviets, by the end of the war.
