Its a bit more complex than that. An EMP, and the residual plasma cloud, would
cause excessive induction that would prematurely set off the klystron switchs
that control the detonators of the various segments of TNT around the plutonium.
Since not all would go off at the same time, the weapon would not, in fact, go
off and no supercritical chain reaction would result, since initiating such is
highly dependent upon the timing of the switches.

Assuming its still in the atmosphere. It would more likely be high in the
ionosphere or in space, if it is in fact 200 miles downrange at that point. Even
if it were in the atmosphere, then the atmospheric displacement would create a
wall of turbulence at the boundary of the cloud, which would cause damage to the
warhead, as well as send it off course. THe unsequenced tripping of the klystron
switches would complete the destruction of the warhead without significant
