I spent 8 years in the USN, including a year in Vietnam. Just because someone volunteered to serve in a dangerous occupation doesn’t diminish their death or sacrifice. I have heard the Left dismiss the deaths of US military personnel with sentiments similar to the ones expressed by you. I find it reprehensible.
Those are the rules when you go into the jungle. And above all else, .gov does not care about you nor should you ever depend on it coming to save you.
Americans know better; our rustic individualism is part of our core.
