God's description of Greece, their army and the manner in which they fought is instructive. Greece's army was invincible in its time. Nobody ever fought with the lightning ferocity and cunning of Greece before this time or perhaps since. They created "blitzkrieg" warfare, which Adolph Hitler openly admitted that he copied from the ancient Greeks.
One historian speculated that the ferocity of the Greek army was produced by their approach to life and especially politics. Even though the Greek system had people filling governing offices such as mayor or burgess, they did not have a representative system like ours. Their society was close to a pure democracy. Each Greek male was taught that he was responsible to participate and contribute to the governing of the community. One result of this was that individual citizens felt responsible to the community, and leadership qualities were produced in them that made each Greek male feel as though he was the leader of his community even though he really was not.
These qualities carried through into their warfare. The individual soldier not only took orders from his captain, he also thought independently to act for the benefit of the regiment. This frequently became necessary in the heat of battle when the leader was incapacitated by wounds or other distractions. Another quickly assumed his role, and there was no loss of leadership.
Thus, a factor that made the Greek fighting machine so invincible was that when their "shepherd" was smitten, the "sheep" did not scatter. The individual Greek soldier would not run off to protect himself from the confusion and danger of the battle when his commander fell. Instead, he helped his unit regroup because he was responsibly committed to its well-being and the accomplishment of its goals rather than his personal well-being.
There are times when it is necessary to flee or withdraw for a while. Jesus said to flee persecution (Matthew 10:23). It is obvious that, on occasion, discretion is the better part of valor. But such times should be only a brief interval during the time of God's working with a person or with His church.

In the Grip of Distrust
The entire Persian Empire collapsed in six years (336-330 BC) under the relentless onslaught of Alexander's troops, who never lost a battle against the larger Persian forces. It was certainly "cast down . . . and trampled" in remarkable fashion.
