A new lap of the arms race is almost always increases the likelines of war, not decrease as every side believes in superiority of its weapons. Equally so, believe that nuclear retaliation we will stop a war "will only hold so until it doesn't" In WWI every side knew how terrible, and devastating the artillery has become — to the point of making the infantry warfare obsolete, and plainly suicidal for an enemy with inferior artillery. It's just both sides mutually believed to have a trump card, and that the one suicidal there was their enemy.
