Many years ago a marvelous advertisement appeared on television. It showed two fat, old men in rumpled shirt and tie, facing off on a hill top and pummeling each other in a clumsy parody of boxing. Gasping and heaving, they staggered around, compelled by the same kind of reasonless hatred that causes them to send younger men to fight and die in the real world. The tag line at the end observed somewhat redundantly that, if those who declare wars had to fight them, there would be none, or something similar. I can’t recall the name of the organization that sponsored the ad, but it was right on the money. Too bad it hasn’t been revived since then.
