Bin-Laden is not rich enough or smart enough to have a nuclear bomb. I believe he already dead. He can't escape from the most powerful country on the face of the earth.
We are all in danger of making a serious mistake. Granted, our leaders haven't helped us on this as much as they might (though they have tried at least a little).
This is not about Osama bin Laden, how smart he is, or even how rich he is (although a few hundred million WILL go a HELL of a long way in a country -the former USSR - where as I recall a few years back, citizens could buy a murder for a hundred bucks).
This is about AL-QAEDA. Osama is a figurehead. Al-Qaeda has many more millions, and even after losing thousands of Jihadists, they still have thousands more. They have backing from rich businessmen.
Are any of these people rich enough or smart enough to have a nuclear bomb? What about a far simpler "dirty bomb"?
Don't think so?
Are you willing to bet your life on it?
