IMO a lot of this problem has been over-blown for political reasoning. I listened to some of the congressional testimony and found that just from the description of some issues - some trivial made out to be exponential - some egregious and heinous misdescribed to be common place and typical where they clearly are not. One example, (and not to make light of the death involved) went from people reporting of being shocked in a shower - to the eventual death being described as "found burned and smoking in the shower" - a description that lends to voltages of the KV range, not a simple grounding and bonding issue or typical.
To me the situation is a circus, and some people are using the kaos to their own gains - political/financial - some very transparent, some not so transparent. My point is that this is the first time the support services for a war has been 'out-sourced' to private companies in a scale this large, maybe that should be rethought... And why should we be rebuilding that country in our own image with our codes and standards that they do not understand. Or hire Americans at top dollar to work on European systems when it does not serve our collective interest of getting the hell out of there. Building bases with European system voltages for Americans - sounds like re-sale potential to me. IMO if the military stuck with using its own support and engineering battalions and stuck to what they know, use, and what they can take with them (i.e. 208/120 60hz temp field wiring) there would be fewer problems.
