Swords to ploughshares

Swords to ploughshares means using military resources that are no longer needed for things that help people live and work. So, putting down our swords (guns, tanks, and other weapons) and turning them into ploughshares (tools to help break up the ground and plant seeds). This means using the metal, guns, and tanks to make tools that help us grow food, build houses, and make other things that help us live better lives.
