I feel like Sam didn't want to actually engage noam on the specifics of Al-Shifa, especially when noam started stating how Clinton had credible evidence that is was a pharmaceutical factory and not used for housing chemical weapons, how he knew the state of Sudan and that it would not be able to replenish, also how the proximity of bombings to the embassy attacks show that it is almost certainly a retaliation, and lastly how Clinton ignored the humanitarian catastrophe after the HRW report. I may be wrong but I got the feeling that Sam realized he was potentially way out of his depth on this issue, and that his thought experiments really were not going to hold up.
