Civil strife is as much a greater evil than a concerted war effort as war itself is worse than peace.

In peace, sons bury their fathers. In war, fathers bury their sons.

A bad peace is even worse than war.

There is no greater evil than anarchy.

In peace, sons bury their fathers; in war, fathers bury their sons. -Herodotus.

War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn to live together in peace by killing each other's children.
