Troops levels in Iraq vs. Afghanistan

[laura888]

From what I'm gathering we have over 100,000 troops in Iraq and less than 30,000 in Afghanistan. (does anyone know exactly what those levels are now?)

Now that we've gotten Saddam out (our reason for invading Iraq, right?) isn't our mission the same for both countries - that is, building democracy and building up the infrastructure?

Why are we concentrating so hard on Iraq? Are Iraqis just more violent? What is the administration's official justification?

I can't find any info on this.
