We are still in Afghanistan now, because W. took his eye of the ball and went into Iraq. The coalition would have finished off the Taliban and been out of Afghanistan before Obama was elected. There’s a pretty good chance that had the US not gone into Iraq, there wouldn’t have been an Obama presidency.
And Saddam and his two sons would still be in power. Saddam had invaded Kuwait and Saudi Arabia. Prior to that he invaded Iran. He had set Kuwait’s oil fields on fire. He had tried to develop a nuclear weapons capability, which Israel took out.
After the Gulf War, we had set up no fly zones in the north and south of Iraq to protect the Kurds in the north and the Shite Muslims in the south. US, British, and French aircraft maintained the no fly zones on a daily basis with no end in sight. Saddam was violating the cease fire agreement. He was also providing sanctuary for terrorists like Abu Nidal. Saddam was a bad actor. His removal was a good thing.
