Agree with ITW. As with all dets, there are +ves & -ves. If you go with the right attitude you can always get something out it. As far as working with the US is concerned, we all know that it can get frustrating at times, but there are some really good guys out there, just trying to make a bit of a difference (if that's possible at the moment).
Spent 4 months working with the US last year. PM if there's any specific advise you need.
