@MattDavis,
Not at all. It is forced. The guy obviously goes to pray at the wall for some other reason than bringing peace. And it is not a reason he would give to a CNN nosey-parker.
It's one of those false jokes which starts with the punch line and is constructed backwards in order to invent the excuse to deliver it.
It's internally illogical as well
because, big word, anybody who would say that to a lady reporter he doesn't know would likely be prepared to tell her the real reason he has been praying at the wall for fifty years.
