Deaths are denoted as integers. They are not in percentages. So numerator and denominator do not apply.
The percentages, as used here to denote ethnicity, do not require knowledge of total combatants.
These data are anything but meaningless.
It makes sense. People die every day. And in Iraq the MSM counts everyone no matter how they died as a casualty of war. With the majority of the Army in Iraq, then all those dieing people get attributed to Iraq and dumped on President Bush’s head by the MSM. Darn we should have figured this out sooner.
