I'm inclined to agree with you intuitively; however, the more I learn about people who were in the military, the more I respect them. I highly recommend listening to the Jocko Podcast and Martyrmade Podcast.

I think the average person is incredibly gullible and naive compared to people who have been in leadership positions in the military.

There are some kinds of wisdom that you simply cannot learn as a civilian.

This is the nature of war, whose stake is at once the game and the authority and the justification. Seen so, war is the truest form of divination. It is the testing of one’s will and the will of another within that larger will which because it binds them is therefore forced to select. War is the ultimate game because war is at last a forcing of the unity of existence. War is god.

Some critiques simply aren't valid unless you have experienced the warrior lifestyle. I've never been in the military, but I tend to respect military people far more than keyboard warriors who don't understand the full scope of the situation.

I'd like to say that an army isn't necessary in an utopia, but in the current moment, it is absolutely necessary. Note that this does not mean that I support wars at all. Smart commanders are very good at maneuvering to avoid conflicts while accomplishing their objectives. This is why they are often sought after in the business world.
