However, after many years of struggle, the troops were withdrawn and Vietnam fell to the Communist party. But this failure had much value.

The experience of the fierce guerrilla warled to changes in tactics that later helped America in other conflicts. Also, the Vietnam failure helped change the American culture. People protested the war and the government responded to the voice of the public. These important changes show the value that can come from failure.
