NATO as a whole is a degraded fighting force, and rules of engagement are just a symptom as is homosexual integration in the ranks.
NATO militaries, with the exception of a few elite outfits, are not killing machines.
Sbrenica could have happened to the armies of any NATO country. We weakened the infantry, gave them weaker rifles, told them to rely on artillery, company mortars, air support, armored transport to conquer through the intensity of firepower. Infantry slow enemy formations and do spotting for support arms. That's what they're trained to do.
Then we give them missions from the old days, when infantry decided battles. 150 years ago [heck 60 years ago] a battlion of Dutch troops would have fought a thousand Serbs all day until relieved. They would have engaged them at distance with lethal aimed fire. They would have lost 1 man in 10 without breaking.
Today you take a NATO soldier, give him a rifle that isn't lethal beyond 600m, train him to shoot fast and often to make the enemy duck, train him to count on mobility and fire support...and then stick him in the middle of nowhere, with limited ammunition, to defend a fixed point against superior numbers, and refuse him air support, artillery, tanks, mortars on the grounds that it would "escalate" the mission, and make sure his officers know the government will fall if there are casualties in Yugoslavia.
That NATO soldier will fail to kill, and will duck a fight that his great-great-great-grandfathers would have celebrated. Because NATO armies are many things for many reasons; but they are mostly, not killers.
The core joke of Hitchhiker's Guide to the Galaxy is that of course no civilization would develop personal computers with instant remote database recovery, and then waste this technology to find good drinks.
Steve Jobs has ruined this joke.
