"And He will judge between the nations, And will render decisions for many peoples; And they will hammer their swords into plowshares and their spears into pruning hooks. Nation will not lift up sword against nation, And never again will they learn war."
This passuk is saying that there since there would be no more use for weapons, mankind will turn his weapons into something useful. Obviously its not that difficult to understand the concept of a sword being beaten into a plowshare. They are both metal and basically the same shape. What about modern weapons like guns, fighter planes, nuclear warheads etc? What uses can we possible get out of them in ymos mashiach?
