"About a month ago, I heard a "credible" expert state in no uncertain terms that a suitcase nuke would level FOUR CITY BLOCKS. "Since then, I've heard very different depictions of the capabilities of the so-called suitcase nuke."
I suspect the amount of damage would depend on where it was placed, at what altitude, and what the surrounding buildings etc. were made of.
Since I have it on your good authority that BL is going to hit us with 20 nukes (but you can't say when or where). Just what changes in my normal everyday life would you reccommend?
You didn't worry much about Y2K did you?
