What is a Mission?

What is the U.S. mission in Iraq? Think Progress notes that it has been redefined every few months, from the early one of ridding the country of WMDs to being completed to not being completed, after all, to being the creation of free Iraq to completing some mission, whatever it might be, for the sake of world peace.

I sometimes write that way, too, when things are not going smoothly and the story veers away from the topic. Then I change the title and pretend that I had another topic in mind all along. But the government shouldn't have the same freedom in doing this as an anonymous unpaid blogger. There are missions and then there are missions. The lives of people depend on how the Bush government defines its mission. I wish they would decide on one definition and stick to it.
