Here is what I have heard so far:
"Why would you get out now?"
"You've been in almost 10 years, only 10 more until you can retire!"
"If you hated the Army, why did you stay in this long?"
"Are you SURE you want to get out?"
"If we were to pull out of Iraq next week, would you still get out? or would you come back in?"
And here is my reason.
I have liked everything I have done in the Army. I like what I do now. I have never had a job I didn't enjoy. It is incredibly rewarding and I sleep well knowing I have worked hard and for a purpose. But... as much as I like the jobs I have done, I would be dishonest if I remained in the Army. I am big on metaphors. Its like this: I like the practice, but I hate the games. If I stayed in, I would find myself not wanting to spend a third year away from my wife and kids. Even if we pulled out of Iraq and Afghanistan next week, China became a peaceloving democratic society, Kim Jung-Il fell over dead and Jimmy Carter became the elected president of north Korea, and Syria and Iran... well, you get the point. No matter what wars are going on, I don't want to be there. Not because I suddenly shun violence; on the contrary, I believe that "the world does not become a better place through happy thoughts and wishful thinking. Peace does not arrive from paper or handing out money. Peace is the result of strength. The world improves through force of will from those who believe in freedom.*" But because I value the well being of my family more than the good I could do in the Army, I must, in order to sleep well at night, leave the Army.
That is a long answer, I hope that the truth of my reasoning can be extracted from it.
