Wow, feenix, I never expected a comment like yours. Enlightening! There are two side to every coin. I honor all of our veterans, sir. Thank you for serving in the armed forces. I am glad you came home alive. My brother served in Nan and survived it.
Chances are some of the NG soldiers did serve in Vietnam, because a lot of Vietnam vets joined the NG after they left active duty. Also, by firing on those unpatriotic fools, those troops were doing their duty; stopping the "enemy" in its tracks.
1770 - Royal troops fire into a crowd of their fellow Crown subjects who are protesting and throwing rocks; killing 5 and wounding others, in what is called the "Boston Massacre".
1970 - 200 years after the Boston Massacre, federal troops fire into a crowd of their fellow citizens who are protesting and throwing rocks; killing 4 and wounding others, in what is called the "Kent State Shootings".
It's interesting how similar these events are and yet the two are rarely compared in a historical context.
In my opinion, there are no comparisons to be made between the Boston Massacre and Kent State. The former was the beginning of a war for independence and latter was nothing but a bunch of spoiled and pampered brats being unruly.
If not for the US's long presence in Vietnam, there would probably have been huge Soviet carrier fleets positioned just off the coasts of Seattle, San Francisco and L.A. And that is the reason why the Vietnam War is the US's most important war.
