Everyone sees what they want to see in the candidates for president. A recent survey on their foreign policies rated them with letter grades, but "foreign policy" is itself a bit of an elusive concept and the results tended to favor what the authors considered to be important. In my opinion the issue is actually much simpler: who among the candidates would be the most likely to lead the United States into another war or wars? Who would be least likely to do so?

The sovereign ability to go to war is the dark side of a nation's foreign policy. It means in practice that the government has been unable or unwilling to use non-violent means of suasion to deflect perceived threats coming from a foreign nation or group of nations. The Nuremberg Tribunal established the principle that initiating a war is the ultimate crime against humanity as it brings with it every other imaginable evil.
