He may just lip service the faith and be using it for political gain.

He certainly doesn't lip service the fifth commandment. His smirking 'saddle-up' attitude when it comes to matters of death (Saddam's sons, the death penalty etc) does not exaclty demonstrate any reverence for that commandment.
I expect that leaders have to make tough decisions that result in death. I don't expect them to revel in it.
