Why the Vietnam war was important

To this day many people still question the reason why the U.S. had entered the war. Some people say that the reason that the U.S. joined the war was because of the news that the North had destroyed on of the U.S. ships. A reason that the Vietnam war was important to history, or made a big impact, was because it was the most recent modern war. This was one of the first times when what the country had to offer in technology was shown. It was when the helicopter was used to fight. It showed how war has evolved. It is was also talked about a lot because of the reason why the U.S. had joined. But the main reason that this war was so important to history to me was because this was one of the first wars where new and better technology was used for war. Also new tactics that were used. Like the Guerrilla tactic that the North used to not have to constantly face the strong forces of the opponents.
