I have heard it said that such usages to produce Pu 239 is not a  
simple process and leaves telltales allowing detection.   As far as it  
being possible I think this is very well recognized as it is used as  
an argument against countries like Iran developing even supposedly  
peaceful nuclear tecnology.  So I doubt very much we are blind to the  
possibility or require a city being nuked to alert us.

What kind of transport are we talking?  Some 60+% of oil used in the  
US is used by cars and trucks.  How many of them could run just fine  
off of electricity generated by nuclear power?
