Does anyone really think these "leaders" such as Saddam or Mr. Kim in North Korea would really use these weapons? They are simply leverage because the one thing they hate is not having power. If any leader used a nuclear weapon he wouldn't be in power for very long after it, rest assured of that no matter who is the President. The "leader" may not even be alive long enough to be thrown out of power. That goes for just about any leader just about anywhere in the world and I would say even the US had to be included. Just think of our situation, we have thousands of potential weapons, just how many of them do you suppose have a chance in hell of being used? Weapons are used as a powerful negotiating tool and nothing else. What could North Korea accomplish with an attack other than an instant and devastating retaliation followed by invasion? They literally would get their 15 minutes of glory and then it would all come crashing down on them.
