Just to follow up on that line of thinking, Dr. Bland, you said it's not particularly useful to compare statistics based on casualties and so on from previous engagements, and I would agree with that. But I think it is particularly important to compare policy objectives and the willpower of governments of the day.
We can go back and look historically at the willpower that was in place when the Korean War was going on and the willpower that was in place during the war in Vietnam, and take a look at the results that happened when there was a lack of public willpower or when the government of the day lacked the willpower to finish the job. Could you elaborate on that for us?
We know the cost of being involved so far has been very great, but could you just elaborate, based on some of the things we've seen in past history, on what the cost of losing would be compared to the price we're paying right now for what appears to be a mission where we're actually succeeding?
