Nuclear Weapons

I believe nuclear weapons are global peacemakers.  Nuclear weapons are explosive devices that derives its destructive force from nuclear reaction, from fission or fusion.  The word destructive is, and has every connotation of, the opposite of the term peacemaker, however, it is necessary to use nuclear weapons when many lives are at stake and when the necessity out weighs the cost. For instance, during World War II, the United States and United Kingdom decided to drop the a nuclear bomb in Hiroshema in order for Japan to surrender and surely the strategy worked: Japan surrendered and peace was awarded to the countries that were involved in the deathly war that killed thousands of lives.  Sure, thousands of lives were lost but the event also saved thousands of lives.   Japan would have hurt and ended many more lives if they did not decide to surrender.  We have to always zoom in the cons and pros and think about the consequences of the nuclear weapons, but when there are more pros, why not give it try? If it can save millions of lives, end a war, or prevent another world war, then go straight ahead.
