Disagree. Hitler had massive amounts of gas and v-2 rockets to deliver it. Up until the end he never gave the order. When both sides have nukes it will be conventional. Ever been in a fist fight? Ever thought about punching your opponent in the nads? No, You know why that thought never crosses your mind even though it is a sure winning move? Because as he is losing his fight due to your below the belt punch he might have enough energy to punch you there too. That is why that NEVER seems to happen.
The V-2 was incredibly unreliable before January 1944.
80% of the rockets blew up on the launch pad.
It would have been an ineffective weapon if Hitler had used it before 1944.
When both sides have nukes it will be conventional
From 1949 to 1991 the Soviet Union and United States both had nuclear weapons.
Why didn't we have a conventional war with the Soviets?
