How is it the most successful when nothing has been achieved yet?
We achieved our mission, to forcibly disarm Saddam Hussein. I didn't agree with this war, but Bush did what he set out to do.
What about how we were going to spread democracy to the people of Iraq? That worked out real well.
The mission may be achieved but it has not yet, so it's silly to call it the most effective war in American history.
Al Queda has lost a lot of their people in Iraq, and antagonized a lot of personnel in Iraq.
But they have killed lot of your troops who they couldn't kill without war on Iraq.
Sorry, but you have to remember the number of deaths that would have resulted had the United States failed to act.
In the case of war on Afghanistan and war on terrorism in general this is true. The war on Iraq didn't prevent anything.
You should have been more worried about North Korea. But what Bush has done? Nothing! And now he is even decreasing amount of your troops in South Korea!
