I ran the simulation as if was still living in my old neighborhood of Riverdale, New York and 50 megaton bombs were hitting 5 cities with populations over 1 million people.
On the map, you can see the horrible destruction--gone is Boston, New York, Philadelphia, Baltimore, and Washington, D.C.
The concentric circles around each blast shows 5 levels of devastation as follows (associated with the colors zones of red, pink, orange, yellow, and clear/outside the blast):
This is not a pretty picture and warrants our consideration of how critically important is missile defense and homeland security is.
This position was advocated by the late Dr. Fred Ikle the former Pentagon official who passed away this week on 10 November 2011--Ikle challenged the status quo policy of MAD asking "Why should mutually assured destruction be our policy?" -WSJ
I, for one, don't like any of the 5 scenarios above and would like to keep our society and way of life going with a strong national security posture that includes the gamut of diplomatic, defensive, and offensive capabilities for safeguarding our national security.

Moreover, with well-known hostile nations having achieved (North Korea) or very near to achieving (Iran) nuclear weapons capabilities, we must take the threats of nuclear attack to us and our allies very seriously or else we can end up with not just scary looking colored concentric circles on a map, but the very real deadly effects they represent.
