One more thought just popped into my mind - Before we have our first theoretical accidental fizzle from a transported nuke in the UK (Approximately 800 million years from now based on 2.4 billion to one odds), it is a gurantee that our earth will be hit with a world devastating asteroid first and there will be no more nukes left to worry about.
Current estimates for our next collision (it may miss us by 40 miles - which is nothing, but that is unlikely) is April the 13th, 2029 (And yes, it is a Friday the 13th). That day, there is a very real chance that life as we know it on this Earth may not exist. I think it is time we start worrying about a real threat.

PS. Nukes are not going to help us on this one - they may only make a deadly threat worse by breaking it up into many smaller peices that are already on a collision course. Something must be done to counter this threat right now!
PPS. Current data shows that it may miss us! By 18,000 miles! Still, what about the next one? This is just one pepple on the beach. We still need a defense.
