Not since the US used the Atomic bombs to end WWII has a nuclear weapon been used in conflict. Considering the madness in the Middle East that seems to be increasing rather than ending, it seems to be only a matter of time before a new nuclear "event" occurrs. Some think that the US is at threat, but I believe that it will occur in the Middle East where the World's greatest concentration of nuclear weapons are kept. Where? Israel, of course. This tiny country, being continually assaulted by insane suicide bombers also has some insanity of it's own. Numerous known nuclear sites. How long before a Palestinian or Israeli fundamentalist decides to "end it all" for everyone and figures out a way to do it? Here's just a few of the sites:
