where do I stand on war?

Yesterday I went to visit a fairly local milatiary base.There are many groups that come from this base that I assist in facilitating and we wanted to gain a better understanding of what these people do so that we can provide a better experience for them at the Woods. It was super interesting but somewhat hard to swallow. Way back in my college days(I know that was oh so long ago:) there were a lot of let's say debatable issues that were kind of in my face. One of those issues was war vs. peace. I took a confident pacifist stance... now I am there but not quite as confidently. One of the first things I saw on base were some high powered guns...ugh. Interesting to see but that threw my brain into a tizzy for the rest of the day. As I listened to these men and women share about what they do on a daily basis to enable the US to defend and fight my stomach was unsettled. I was forced to contemplate my assistance in empowering these people to essentially be more effective at sending people off to war.
What IS my role? Am I indirectly supporting war? And should I stop? Or is war a fact of humanity and by helping these people do their jobs more effectively am I indirectly helping protect those who fight every day? Though I am answerless, my convictions are not strong enough to stop doing what I am doing... but I wonder if they should be? What do you think?
On another note I did get to ride in a hummer AND sit in the driver's seat...pretty sweet when I don't think about why hummers exist in the first place...see pics...
