"The Weapon Too Dreadful To Use" is a science fiction short story by American writer Isaac Asimov.

However, as the domination by the colonists increases, elements of the Venusian resistance obtain the weapon and use it on the colonial cities and their population.

The weapon works by disconnecting the brain from the mind, and within a short time, the Venusians take back control of their planet from the defenseless colonists.

In The Early Asimov, Asimov speculates that Amazing might have bought the story because the magazine needed a story quickly, since "The Weapon Too Dreadful to Use" was accepted in February 1939 and published in the May issue.

[1] Frederik Pohl pointed out to Asimov that after the Venusians destroyed the weapon Earth would be free to reconquer Venus.
