"All weapons are boomerangs" is a popular antiwar and disarmament slogan referencing the fact that a boomerang comes back to the person who threw it. The boomerang effect is when a country creates weapons, which they then have to face in the hands of their enemies in the next conflict. This slogan claims that all weapons a country creates or uses are likely to come back to haunt them regardless of whether they fall into enemy hands.
