I completely understand that it is hard not to think in such a way! I struggled with it at times while I was serving on active duty and especially when I was in the region in 1986 and this was with the best Commander-In-Chief (Reagan) that I could imagine!
I do believe that at this time, our involvement with Iran are for good reasons, that President Trump is committed to victory and cares about the well-being of our service men and women who may find themselves over there. My main concern though is if things are not concluded by 2028, whoever proceeds President Trump (and I do pray it is either Vance or Rubio) may turn everything into an absolute "Charlie Foxtrot" just like they did in Vietnam, Somalia, Iraq, Afghaninstan, and so forth! The "Military Industrial Complex" is very real and my Lockheed 401K grew significantly following 9/11! My ex-wife got most
I was very idealistic believing I was there to fight communism, to "Kill Commies for Mommie and Ragheads for Ronnie" but foreign policies change and shift depending on which political party happens to be in power. I left active duty in 1991 and joined an active reserve unit for a while but when Clinton took office, I was quite worried about whether I would be able to obey his orders so I transferred to the inactive reserves and never went back! Long story short, you have to learn to be A-Political and realize that what you are doing is a "Job." It is not that you are loyal to a President or even the United States. The main place your loyalty needs to be is to the person who is fighting alongside you! I know that servicemen and women involve themselves both physically and emotionally and the top brass tries to paint a "rosy picture" of all the "good" they are doing and the people they are helping. Those who serve "in-country" are especially involved and is the reason why they serve multiple tours even after sustaining injuries that likely qualify them for medical retirement! I believe that these are the ones who end up getting really messed up and disallusioned.
Huk had a good idea about joining the Coast Guard. They are more law enforcement oriented (drug interdiction, maritime law, etc.) and aside from blowing up a "drug boat" ever so often, I don't see them being involved in any protracted combat deployments or whatever.
