No sir, I used to work at KBR, Inc as an engineer. I got sick of spending an hour or two, morning and night, being driven in a bus to a work site while locals took pop shots at us and planted IED's in the road. A man can only take so much of that, regardless of the pay.
I've spent time in both Iraq and Afghanistan and I can tell you that what is happening in both of those countries is completely different than the media is reporting. Though, my ass was mostly protected by PMC's, I did spend a lot of time around the military, and those boys are not over there for any other reason than drugs and oil. Any conflict they do have is brought on themselves for running the locals off their own poppy fields and land. It's a mess.
Believe me, it's being built. I've seen it with my own eyes.
If they are not too embarrassed to tell you the truth, you should sit down with them when they return and ask them what it's all about over there. I doubt low level combat soldiers will know the master plan, but anyone who has spent a lot of time there should know the who, what, when, where and why of the occupation in Afghanistan.
When I finally had enough and decided that was not for me, at that time, they were discussing similar construction projects in Iran.

There are also plans in place for various parts of Africa. One thing I can tell you from my years working at KBR, is that the master plan for oil is larger than anything you can imagine. I've seen plans on a global scale that will have the USA controlling most of the worlds oil within 10-15 years.
The media has spun this "war" and it shames me as a human to hear about it. It is not the truth, not even close to the truth. It's about greed.
