Okay, Plane, here you go...
Rather than cutting back in Afghanistan to waste our time invading a country that had nothing to do with the attacks on us, we should have kept after Al Qaeda in Afghanistan. Bush should have kept his promise to keep after Bin Laden, who was responsible for 9-11, rather than wasting time on Saddam, who wasn't. We could have put many more troops into Afghanistan and pursued Al Qaeda there to the gates of hell if need be. If they ran across the border to Pakistan, we could have given Musharraf X amount of time to catch them and turn them over to us, or kill them, or we would go in after them. Why worry about upsetting Musharraf, our 'great ally in the war against terror', if he is so ineffective he can't control his own border anyway?
Ah, you ask, what about Al Qaeda in Iraq...
Here's the answer to that one - Al Qaeda wasn't active in Iraq under Saddam. They weren't active there until we removed Saddam from power and screwed up our invasion enough to leave a power vacuum for them to become active in. The only reason we're fighting them there is because we gave them the wide open opportunity to come in there.
Now if any of that is unclear to you or you have a question, just ask. Quit trying to play Sirs and tell me what I'm thinking.
