Ethiopia and Eritrea was touted at the time as being very successful—probably more along the lines of classic peacekeeping, the separation of two state parties. That's why, but also because of the strong leadership and the strong forces that were sent in.
I want to make one comment that ties back to Mr. Bezan's remarks and a favourite saying that I recall of General MacKenzie: “If you're going to a knife fight, take a gun.” I think that sums it up. Yes, if you're going to put boots on the ground, don't mess around with, “Oh, we're restricted to 300 or 500.” Send a battle group. Make sure the APCs, the armoured personnel carriers, go to Sarajevo. Even if you're told not to take them, take them. Do all the stuff. Even if the UN is not going to pay you, take them.
