Those aren't facts. That is all speculation from 2 years ago. There is one fact in that article, the fact that there are now 19,000 armed security contractors. This number is much, much lower than the amount of troops in the country. There are a lot of contractors, but those are contract workers, not PMC employees. This is a huge difference than the point you're trying to make. Laundry workers and cooks don't wage war for the government.
Citation please. I don't believe this to be true based on first hand accounts of people who have been to both of those places.
