Are the borders in Iraq secure? Judging from the fact that most insurgients are coming from other countries, I'd say no and we're not succeeding. How many Iraqi security forces are trained? Judging from the fact that we never hear anything from this administration on this issue and that they have exagerated the facts about it in the past, I'd say no to that one as well. If American troops left, all out civil war would break out and the Security forces trained there would collapse instantly. Withdrawl troops? There will always be a military presence in Iraq the same as there was in Germany and Japan after WWII and Korea after the Korean war. When you say "wear down insurgency," not to personally attack you but Cheney said the same thing a couple months ago and several commanders over there say otherwise. The insurgency is as strong as its been and what people don't realize is that the war is recruiting new insurgients and potential Al-Quaida operatives in great proportions. The war in Iraq isn't detering terrorism; it's encouraging it!
Make them come out of hiding so we can kill them there, rather than at home. The more energy they are putting into fighting us in Iraq, the less time they have to plan terrorist strikes in the west.
The notion that fighting the terrorists in Iraq means that we won't have to face them on the homeland is specious reasoning. By using this logic, I could say my computer keeps me safe from mad cow disease. It doesn't, but I don't have mad cow disease, do I? What about the terrorist attacks in England? What about the terror cells in uncovered in California? Just because they're fighting there doesn't mean they can't do anything here.
