Nails of Peace

Buy a large nail or a spike like those used for constructing railroad tracks.
Dip it in gold, or silver, or copper or blood.

Engrave on it words of peace only.
Attach a harness and equip it with a small parachute.

Fly over a war-ravaged country.
Drop your emissary of peace out of your airplane.

Repeat until wars become a distant memory.
