US: Used atomic warfare to end conflict over the entire pacific and save millions of lives, though we did it with great remorse. Please note the atomic bombs we used were fairly small scale and did less damage than the firebombings. The use of the atomic weapons on the Japanese mainland BROKE THEIR IDEA OF TOTAL INVINCIBILITY AND STOPPED THEIR CONQUEST OF THE PACIFIC AND CHINESE TERRITORIES. The US, as a result of the cold war, went on to do SALT I and SALT II treaties.

NK: Threatens the use of nukes to initiate warfare and uses them as a threat. Nukes are their intended first resort.
