And here is the deeper problem: My remark that you owe veterans an apology has not been responded to by you. In fact, it was downvoted into the negatives and you are like the fifth person to come in here to essentially shoot me down and treat me like I am stupid and do not have a real point.
Meanwhile, you posit "if we could all just get along."
You do not even know how to communicate effectively or engage someone with skin in the game with genuine respect when the only thing at stake is words on a forum. That is your answer as to why military spending is not merely frivolous.
You have a long way to go before you, personally, are in any kind of position to advocate that we all just get along. Perhaps in your journey, you should note that Shaolin priests were fearsome warriors because they believed "A man of peace must be strong."
Best.
