We have eliminated a head of state who had links to the terrorists who were behind 9-11, who despised us, who would have done anything to pay us back for the ignominy we handed him in defeating him in battle.
We have done so under the watchful eyes of OTHER despots who now feel the cold finger of death on their spines and , consequently, are somewhat more inhibited in backing terror than they had been previously.
We have established a nascent Democcacy in a region of the world that fears more than anything a successful democratic state (which will strike a more deadly blow against them than limitless military divisions ever could) and which puts our death dealing military in close proximity to those above mentioned despots.
We have attracted many of the most motivated jihadists in the world to Iraq and have been killing them at record ratios.
We have SERIOUSLY cut off many of the terrorists around the world off from one another (INCLUDING OSAMA), even as we learn by fighting them thus becoming much more proficient at defeating them, which will serve us well when Iran is behind us and we can focus on others who are in fact deserving of our attentions.
We have come this far without seriously discommoding very many Americans. I haven't missed a meal or lost a single nights sleep while all of this work has been done. Have you?
If the Osama qestion troubles you go find him yourself. I think he's dead and I wouldn't be surprised if the President at least suspects that he is.
Not the ones who are determined to come here and hit us in our streets. If that was my goal -- as it's the goal of a number of terrorists, no doubt -- I wouldn't be stupid enough to get diverted to Iraq, I'd go directly to the US. If you think such a simple calculation is beyond the intelligence of terrorists, then you're following Rule 1 of the How to Lose a War book: Always assume your enemy is stupid.
