Throw a rock in a crowd, and you will likely hit someone who has had relatives, friends, etc, who has been over there. Your situaiton isn't special, those who fight are special, but those who sit at home and talk about it are not.
And it doesn't give you any special insight, either.
Got a neighbor who spent almost 30 years in military Intelligence, retired as an O6, and guess what, he is still learning that things he "knew" during Vietnam wasn't always complete or true...
One thing I noticed in Vietnam that is being duplicated in these wars right now. Too many of OUR troops are getting killed while too few of our Arab "allies" are letting us carry the load. Too many of their men aren't fighting their enemies. They need martial law, a forced draft, and prison for draft evasion before they can show us that they deserve our help....the taliban won't go away, or Al Queda, not until they are all dead...and only native troops can do that...
