I think the right should say what answer they'd praise from the left. They say that all the options the left can offer are bad - and therefore republicans are right.
If the left says 'pull the troops out now', they make the case no ME nations want that and it'd have terrible consequences.
If the left says 'pull the troops out asap, but make things somewhat stable first', they say 'but that's the same plan as Bush!'
If the left says 'stay fully committed as long as it takes to make sure Iraq is stable', they also say 'see, Bush was right all along, in spreading democracy there'.
If the democrats come up with some creative approaches, anything from negotations with Iran to UN efforts or other things, they say 'that won't work, see, you can't trust the democrats not to do horrible things, you need the republicans'.
So, there's no answer to this question for the right; it's only asked to let them say 'see, we need the republicans in charge'.
Well, where's the accountability for the bad policy - if the republicans pay no political price for getting things so wrong, then what's to stop them from doing it again and getting rewarded with continued political power again?
We don't need attacks we need solutions.
The attack may be the solution. It's called accountability. Attack the republicans for their mistakes, and get rid of the incompetent, corrupt people now in power, and replace them with democrats who will return America to the nation of freedom, representing the broader public, with responsible policies, and punish the wrongdoing by republicans.
It could be said that whatever the democrats do, withdraw or stay or whatever else, it's better that the policies are done by democrats who at least have the right interests, and that the mistakes are punished to discourage their being repeated.
But right-wingers are not driven by what's good for the world or the nation, they're driven by their self-identification as right-wingers, and they simply want to keep power. This is why if democrats ran on a platform of something wonderful, the right-wingers would simply find something to criticize about it.
Good example - one of the best government policies in the last decades was funding the development of the internet; the leading politician fighting to do so was Al Gor, and the republicans could not find a single good word to say about him, instead only criticizing Gore for something he didn't say.
That's why it's up to the American people to choose between rational, good politicians in the democratic party, and the crazy, irresponsible, harmful policies of the right who are very good at representing the few ultra wealthy/corporate interests, and lying to and harming everyone else.
