From Surfer Bettle:
The internet seems to indicate that Iraqi and Afghan immigrants are a reality for Germany which appears to have approximately 100,000 registered Afghan immigrants of varying demographics.
You have touched upon an issue that I suspect is debated elsewhere in development sphres - the exodus of trained manpower from developing countries to the developed world. In the UK this is particularly prominient in the health profession.

Back to the agricultral theme. What has happened to the skilled manpower which has returned to Afghanistan, including businessmen from the USA as reported a few years ago?

That would be an interesting metric for the success of COIN.
