OK,
Comparisons:
Vietnam--Highest Troop Levels in 1968 at roughly 450,000 U.S. forces in country. Losses that year: approx. 14,600 KIA, 87,400 WIA.* That's a 3% KIA rate.
Iraq--Current Troop Level at approx. 125,000 in country. Don't have YTD deaths. But, total casualties since March '03: approx. 2,100 KIA, 22,000 WIA*. Troop levels have fluctuated between approx. 150,000-120,000 in country throughout this period. Dividing total KIA by 3 = 700 per year average = .4% KIA rate.

I understand what you're saying--more people in country mean more deaths naturally. But, a "per capita" rate doesn't count here, because we're talking about people's lives. It doesn't matter how many get killed, their have equal worth, regardless of percentage. We're spending a much smaller amount of youth and treasure on this one.
We're drifting off topic a bit, partly my fault. IIRC there's something like 400 million military aged males in China. We don't have enough bombs or bullets in the current inventory to deal with that type of military potential, nor do I believe the industrial potential to match theirs. And no one in the world is going to let us just turn either country into a nuclear wasteland. Fighting China or N Korea (or possibly both at the same time?) will be no cake walk, despite our technological advantage. 400 hi-tech aircraft versus 2,200 obsolescent aircraft--I say advantage to the obsolescent aircraft. And, I know we have more than 400 hi-tech aircraft, but for a fight against China, where you going to base 'em? Kadena AB in Okinawa doesn't have enough ramp space. MCAS Futenma in Okinawa doesn't have enough ramp space--not that either Okinawa field would last that long. Guam--lots of airborne refueling from there. Japanese airbases would last only a little longer than Oki. The only real advantage we have IMO is with Blue Water Navy. And I'm not sure that it would be decisive.
BTW Choocha, where do you work?
