The very premise of the whole peacekeeping thing is flawed. You see, because a country is in the UN, we can't tell them:
"We're sorry, Mr. President-For-Life of Absurdistan, but you're a Third World hell hole whose army is stocked by illiterate gutter sweepings who were given a choice between prison or the infantry, and your patronage-based, class-conscious officer's corps is too professionally incompetent and riddled by graft and corruption to control them.No, in a UN where Syria can sit on the Human Rights committee, we have to pretend that all countries are equal.
You can't even keep the peace in your own country, so we'll have to politely decline your request to send The President's Own 3rd Light Infantry Regiment to join the UN peacekeeping effort in Upper Revolta."
Not every country has the same military traditions shared, to one extent or another, by most of the Western democracies. My friend Oleg is from Russia, which compared to Backwoodistan or East Lemuria is practically the same as us culturally, and he was mildly surprised to meet a number of current and ex-servicemembers who were not only literate, but actually cultured, despite being NCOs or even junior enlisted men. The concept of a poetry-reading sergeant was foreign to his experience as a youth in the USSR. Imagine, then, the further gulf between civilization and the members of a military who are little more than street gangs with uniforms, and you wonder why anyone's shocked when they engage in a touch of rapine when sent to "keep the peace" in a foreign land.
