Several months later the second stage : “Since we’ve already gotten ourselves into this jam, we should get the fighting over with as quickly as possible. Adding another thirty thousand men isn’t going to do it. We need at least another army to shut off all the borders.”
Five or six months later, the third stage: “There is something desperately wrong here. What a mess!”
Then, half a year or so later, the fourth and final stage: “We’d be wise to get the hell out of here – and the sooner the better.
