to OP: If a nuke drops on your head, I guess 100 OZ silver will not save you and your family. My point is that you just can't worry so much in your life. Life is full of risks, even when you walk in street and when you drive, but lives go on and we still walk and we still drive. To me, the chance US dollar suddenly goes to zero in 5 minutes is less than someone misfires a Nuke. I agree dollar may slowly decline its value, maybe over years, but we will have plenty of time to react.
