This is actually a good point. I do agree with your response re: multi-tasking, but even though I'm involved with multiple projects at work, I still have to show progress in all of them.
We may not be done, but we are showing progress. We've toppled the taliban, and we have so far captured several top level Al Qaeda members. And while Osama may still be at large, it would seem that we're gaining on him, and that his days are surely numbered.
I call that progress.
