Conner talked a great deal about the importance of the second paragraph, the commander's estimate of the situation, which involved assessing each open course of action—and each countermove available to the enemy. The less one knew about where the successive steps of a battle might lead, the less one could formulate a sensible strategy and, therefore, the less willing one should be to jump into a violent fray of mystery.
I've been thinking about this for a while. The time to worry about things like ethnic cleansing and increased Iranian influence is before you start the war. You can't put the genie back in the bottle.
