Basil Wolverton's Planet of Terror #1

Synopsis

In 2423 a pacifist scientist attempts to halt the plans of the united Earth government from attacking the newly-discovered peaceful Martians. He tells the ruler that his magnetic force weapon's blast is too powerful for Earth and must be tested on the moon. When no blast occurs the ruler thinks he's been tricked. The scientist reveals the blast occurred on the moon's dark side, shifting it out of orbit and crashing into Earth. After playing havoc with the tides the moon shatters, killing everyone except the scientist, who believes he was justified by sparing other beings from Earth's tyranny.
