It has been said that war is a genetic trait in the Vietnamese people. Their history is one of continual conflict. Their land has been occupied by many foreign armies. During the 13 century, Mongol hordes led by Kublai Khan, occupied the abandoned Vietnamese city of Hanoi only to retreat in the face of an abundance of tropical diseases. General Vo Nguyen Giap, commander of the NVA during the war with America, was strongly influenced by Dao's strategy, and he also had the determined support of the North Vietnamese people.
Time is always in our favor.
Our climate, mountains, and jungles discourages the enemy. Naturally the NVA claimed victory, and this claim seems to be logical under the circumstances.
