If by some chance Tariq is a true Christian he would have to tell the truth. If he did then Saddams' WMD's would be verified as nearly non-existent compared to the reports on the contrary.
With Tariq out of the way then it would help with Saddams' trial.

Sounds like a plan. Can't give any advantages, if that's possible, to Saddam in the trial.
