The National Review -- yes that National Review as in NRO online -- has just run an article by Mario Loyola which essentially explains why Blackwater and the other PMC should leave Iraq, and even uses the word "mercenaries" right there in its title: Mercenaries vs. Counterinsurgency: Blackwater could be a worse problem than you think.
The best way to protect your forces in a war is to the win and get them out. If, in the meantime, that requires that soldiers throw themselves at certain death on the beaches of Normandy — or on Haifa Street in Baghdad — then that is what they are expected to do.Amen.
And today in Iraq, that is exactly what they are doing. In countless situations, they fight against their survival instincts and lower their guard so the population feels safer. They refuse to return fire when fired upon if they cannot positively “ID” the shooter. They offer their lives so the insurgents don’t find a way to take advantage of their firepower. Their willingness to give their lives for the mission is what the military is all about — and it is what the counterinsurgency strategy presumes most vitally.
The problem with security contractors is pretty clear: Central Command isn’t even sure how many there are — according to one source in the Post article, there could be as many as 50,000. They are heavily armed, and use their best judgment of what is necessary for their own protection — not for winning the war. The COIN [counterinsurgency] strategy doesn’t apply to them. But because neither the insurgents nor the Iraqi people distinguish between contractors and soldiers, what you have in Iraq today is a situation in which perhaps 25-percent of the perceived coalition "force" is operating outside the chain of command, and in violation of the stated strategy.
That means that in the neighborhoods of Baghdad, our soldiers are exercising deadly restraint to win over the population, day after day, for months and weeks on end — and all of their work can unravel, all of their sacrifices thrown to the wind because of just one shooting incident carried out by private mercenaries. This is unacceptable — not least because the resulting effect is an increase in risks for our soldiers.
UDPATE 9/28/07: From The New York Times:
Participants in a contentious Baghdad security operation this month have told American investigators that during the operation at least one guard continued firing on civilians while colleagues urgently called for a cease-fire. At least one guard apparently also drew a weapon on a fellow guard who did not stop shooting, an American official said.
