As long as there are sovereign nations possessing great power, war is inevitable.

Albert Einstein
[With all due respect to Einstein's insight into physics I must point out his insight into human nature and politics was lacking. We are currently at war not a sovereign nation but a group of religious fanatics that barely recognize national boundaries and have essentially zero in the way of "great power" as defined by modern military metrics. And war has existed, and still does, when the "nations" are nothing more than large tribes equipped with spears, bows, and arrows.

The lesson to be learned from this is that however brilliant someone is in one field of endeavor that is no indication of their ability to contribute in another area. One's reputation in any given area must be earned.--Joe]
