Answer:
In the United States, the effects of the Vietnam War would linger long after the last troops returned home in 1973. The nation spent more than $120 billion on the conflict in Vietnam from 1965-73; this massive spending caused the widespread inflation, exacerbated by a worldwide oil crisis in 1973 and skyrocketing fuel prices.The war had pierced the myth of American invincibility and had bitterly divided the nation. Many returning veterans faced negative reactions from both opponents of the war and its supporters, along with physical damage including the effects of exposure to the toxic herbicide Agent Orange, millions of gallons of which had been dumped by U.S. planes on the dense forests of Vietnam. In 1982, the Vietnam Veterans Memorial was unveiled in Washington, D.C. On it were inscribed the names of 57,939 American men and women killed or missing in the war; later additions brought that total to 58,200.

The correct answer to this open question is the following.
During the High Middle Ages (100-1300), France and England formed unified states while Germany remained divided.
This happened because the governments of France and Great Britain created vast kingdoms that increased the power of control in some European regions. And this was the result of solid leadership in each of the kingdoms.
The problem in the case of Germany was that it never has a true leader -as was the case of France and England- who could be recognized by all the tribes. No leader was strong enough to unify the different territories in Germany.
