darla.... this is simply my opinion...
1) Yes, I think going in was inevitable. The sanctions were not working. The UN was ineffective for 12 years. I think that would have continued.
2) That said.... the timing of the war was wrong. We should have stabilized Afghanistan with overwhelming force and hunted Bin Laden down first. Second, the planning of the war was horrible. We never should have disbanded the Iraqi army. Our exit strategy was also poorly planned. Bottom line, Bush screwed the pooch. I don't think that makes going in the wrong decision, but the timing and handling of the war were mistakes.
I see...well I disagree with your 1), but I was just curious how you felt about the war, since every republican you picked other than Hagel, are war supporters.
