Is the world at it's most dangerous point in history or am I paranoid?

I'm 33 and I remember being scared in 1985 when I learned that U.S.S.R. had nuclear weapons pointed at us and we on them. I wasn't around in the 50's and Cuba Missle Crises but I've heard J.F.K.'s recordings and Robert MacNamara's retelling of events. That being said, Nuclear Proliferation is the worlds most serious issue and all the leaders in Washington, D.C. know it. I've been watching C-Span and I've heard Madiline Albright testify before congress and I got the picture. I think the Genie's out of the bottle and it's just a matter of time before one of the countries who have nuclear capabilities nuclear bombs Isreal or someone else or there's a revolution in one of these countries and the nuclear bombs fall into the hands of some crazies and they blow up the Sunnis or the Shiites or something and start Nuclear War. Am I right? How can I sleep tonight? I'm worried.
