Even in the desert, the Jews would not stop with the golden calves. God nearly let the whole lot of them perish in the desert, he was so angry about their idolatrous ways. Only when he had a new generation, born in freedom, that didn't complain about the food, did he lead them to the promised land. For you liberals still reading, this is all extensively covered in a book known as the "Bible."
(Also this week, we celebrate a fast-track to freedom that doesn't require 40 years in the desert, but as I recall, the suggestion that we convert Muslims to Christianity was shot down early on in this war.)
If you want a shorter rebuilding process, then we're going to have to wage less humane wars. The enemy -- as well as innocent civilians -- must be bombed into quivering terror. Otherwise, we displace aggression but don't destroy it.
Americans are weaker for having seen that kind of carnage in World War II. Recall that the Worst Generation was raised by the Greatest Generation. That tells you how awful war is. The Greatest Generation was so exhausted by the war, it didn't have the spine to stand up to pot-smoking, draft-dodging hippies occupying administration buildings. But enough about Bill Clinton. If we're going to have humane wars, they are going to take a little bit longer.
That wouldn't be so bad, except that it gives fifth columnists more time to demoralize Americans and convince them that we are losing a war in the paramount struggle of our time.
