We are entering the age of PUSH BUTTON WARFARE. You only need to push a button and an army or enemy city will be destroyed.
A single plane flies over a city and WHAM! the enemy capital is destroyed. The only work for the Army will be to move in and keep order among the survivors.
This new ATOMIC AGE is actually an amazing thing really. Wars will last only hours or at most days. A resolution will come quickly as the enemy cities are vaporized under an atomic cloud.
