Which big bang ? A few superpowers may have tested the occasional EMP
weapon with 'interesting' findings, but no one ever deployed one -
they all realised the potential for damaging thier own infrastructure
as well as the target's. And contrary to all the popular sci-fi films
and myths of the era, a normal ground-burst or even air-burst of a few
MT does not generate damaging EMP. It has to be a true exo-atmopheric
explosion at a height to do practically no other damage, and of a
mechanism yielding mainly high energy gamma / X-rays to generate the
necessary Compton scattering.
The stories put-about back then were incorrect and partly propaganda,
but also genuine misunderstanding of the respective countries'
techology capabilities, and their modus-operandi
