I'm going to reply privately to this, so as not to reveal anything to jihadist lurkers.
As far as responding to a problem, think about this:
Several small nukes in Manhatten would create hundreds of thousands of burn casualties.
Our burn beds are numbered in the thousands for the entire country. We couldn't respond properly to the wounded from just one event. The system fails pretty badly right there.
And a large number of them are in NYC and would be destroyed in the attack.
Where was your private reply? You just gave jihadis another idea! :)
