1) No. I am fairly certain there will be at least one major city hit with WMD in my lifetime though.

2) Pretty certain no chance of a 'World War'. Equally certain of smaller uses of WMD.

3) Within 10 years, I say 30%. Within 50, probably 70% (chance of my #1)

4) I would say North America has about a 50-50 chance of being the target

5) As to the case of a large scale WMD war, those of us living in major metro areas are basically screwed. In the case of a single use WMD on a city or region, well, that can be mostly treated like a natural disaster and prepared for and survived in a similar way.
