I believe that many war would not have been fought had the rulers or people responsible for the decisions to go to war could do it over. Clearly that is not the case with the present Iraq war.
Why?
Because the cost of war at times far exceeds its original justifications or expectations.
The decision for war must include a cost-benefit analysis to the extent on can predict the future. Michiavelli said that one can choose when to start a war, but not when to stop it. The course of war is inherently unpredictable, which should make the decision to avoid war easy except where the benefits so outweigh the costs that no other choice makes sense.
No one goes to war over minor injuires or insults, or should. The injury must be major or the predictable cost of war low to justify war.
Given these thoughts, imagine this hypothetical. You are the king of German feoderati that have been given lands inside the empire on the condition that you guard the borders long enough for the nearest Roman army to come to you aid. One day, the Huns appear on your border in overwhelming force and give you this ultimatum: let us pass and we will do you no harm.
If you let them pass, you will have violated your agreement with the Romans. They may later come back to expel you by force from the empire. But if you do not let the Huns pass, they will certainly wreck extreme damage on your people even if you are able to slow them down enough to allow the Roman army to arrive and to drive back the Huns.
What choice do you make? Allow the Huns to pass or abide by your agreement with the Romans?
