I beg to disagree re Cu Chi tunnels. As an American, I understand that there is bias in Viet Nam about the "American War"- but the tunnels are a case in point illustrating what the American soldier was up against and why the Americans eventually left Viet Nam. The US greatly underestimated the tenacity of the North Vietnamese soldiers who believed they were fighting the enemy and they were fighting for their country. The power of totalitiartian government and propaganda is important to witness. I spent 3 weeks in Viet Nam this past summer and I am itching to go back ASAP. If you get a chance, go see the film The Fog of War which is an interview with Robert McNamara- and listen to his reflections on the war.
