the first job of any democracy - is security. if it can't secure itself, it can't sustain itself.
the iraqi police forces - are generally regarded as just a bunch of guys looking for a steady paycheck. the army is in much better shape, but still lacking. and the government apparatus is loaded with problems - look at the new thread running now, Maliki just fired 3000 employees for being loyal to the militias and not the elected government. this is what it means to be "not ready".
They should have been executed on the spot. That's 3000 more added to the streets.
Sure there are problems.
But what is better to have than democracy as you try to sustain it against the disruptors?
(Especially, when most in the country want it)
