Vietnam is a jungle. You had jungle warfare. Kuwait, Iraq, Saudi Arabia, you have sand. [There is no need to worry about a protracted war because] from a historical basis, Middle East conflicts do not last a long time.
During my three years in Vietnam, I certainly heard plenty of last words by dying American footsoldiers. Not one of them, however, had illusions that he had somehow accomplished something worthwhile in the process of making the Supreme Sacrifice.
Cranes carry this heavy mystical baggage. They're icons of fidelity and happiness. The Vietnamese believe cranes cart our souls up to heaven on our wings.
