The Starfish Prime nuclear test on July 9, 1962 caused massive fluctuations and degradation of the Earth's magnetic field. This field is largely responsible for redirecting the Sun's solar radiation. We know that Mar's atmosphere was largely attenuated as a direct result of that planet's electromagnetic field degradation. This hypothesis is that a series of nuclear detonations in or above Venus's atmosphere would severely weaken that planets electromagnetic field allowing solar radiation to attenuate the atmosphere.
The attenuated material from Venus' atmosphere would create a temporary interplanetary "space haze" blocking solar radiation on the closest planet opposite the source of the solar radiation (Earth) when the orbits of the two planets are in optimum alignment. Is this feasible?
