Yes, American soldiers should return to Iraq to fight because Iraqis are being forced from their homes by conflict, because it would do a lot to help the Iraqi people. That it is falling apart now shows how effective American soldiers were when we were there. We can restore peace to the region.
No, I don't think that American soldiers should return to Iraq and fight. We have already been in the country for far too long, we went there on false pretenses and now the situation has gotten far out of control. It should now be left to the inhabitants of Iraq to sort out.
I don't think America should go back to Iraq because they have de stabilised the region enough already. It's going to take around 20 years to recover the society following the period of time the troops were in Iraq. I feel the damage has been done and returning will only make it worse.
So much time and energy has already been spent by American troops in Iraq, trying to create order and stability, and the moment they leave it begins to crumble. Rather than troops, more needs to be done to support the Iraqi government and troops to prevent further conflict, rather than charging in and clearing up one mess only for another to appear as soon as the sight is clear.
