Distrust of the government is what this nation is founded on.
The military is not for everyone, and serving or not serving has nothing to do with with ones patriotism IMO.
I do think that if one has served, they will come away with the real life experience that government is full of idiots, and government is simply incapable of of doing what those believing in a conspiracy theory think it is capable of..
Look at Obamacare, how can anyone believe a government incapable of roiling that out, could also be capable of running a multi-generational conspiracy? When it comes down to it, distrust of government, in my belief, is based on the fact that big government doesn't work by design...it makes no sense to me to believe a government that doesn't work everyday is capable of running a 75 year a conspiracy ... 
I think you fail to understand the realities.
The oligarchy is a fairly small, group with intensely shared goals and the power and wealth to carry them out--in a diversity of ways.
They have hired child prodigies--typically at young ages--in a variety of fields. Money is no object at all. They have particularly hired a lot of very sharp psychologists and sociologists who have helped them manipulate the culture and society toward their goals with a minimum of awareness and a minimum of set-backs.
One of those psychologists was a White House 'Fellow'--though she was a woman--in Jimmy Carter's reign. She was one of my PhD profs. I just happen to know a fair amount of what I'm talking about from first hand dialogues in addition to reading 10's of thousands of pages of documentation on the oligarchy's goals, strategies and efforts.Note: I'm not per se saying your responses fit the below description at all--am spring-boarding off your responses to make a comment.All this hostile, bullying, purportedly 'obvious' logic against 'conspiracy theories' is unmitigated uninformed ignorance that will turn out to be brazenly embarrassing because the evidence has been piled several stories high in plain sight for decades. There's NO 'theory' to it. It's
ABSOLUTE FACT as documented by warehouses full of evidence for many decades--certainly the last 150 years and in some cases--from the beginning of our USA.
Even in terms of the U.S. military . . . yeah, run of the mill stuff tends to typically be a Laurel & Hardy mess.
On the other hand, when a black ops group decides or is ordered to do something, they can pull it off amazingly slickly.
The UFO crash retrieval teams as outlined by my close relative are a case in point. There are occasional mess-ups but on the whole, such operations go off with little to no hitch and amazingly quickly sanitize the site and neutralize the witnesses with threats and/or ridicule.
So, even with the military--it's a mixed bag.
Certainly tyranny and socialism etc are messy, inefficient etc.
Yet, as Hitler showed . . . he got the trains running . . . and, was well funded by Bush's grandfather to insure Hitler's success. Besides, he and Mao, Lenin, Stalin (also well funded by the oligarchy) were great trial runs for the tyranny they were planning for the whole planet.
