>I'm frankly a little weary of fighting for a country of overweight non-voters.
the act of non-voting is itself an action, it is a statement of distrust, disillusion and or disenfranchisement from the system

Look up jus ad bellum. I think if you look at past wars in which the US was the aggressor, and stack them up against the principles of just war, you'll find they often meet more criteria than a lot of people care to believe. Regardless, the military is an instrument of the people. If the military does things you disagree with, vote. Campaign. Lobby. Spend your time and money influencing other people to get off their asses and vote.
