That pope seemed to be a pretty nice old boy, and downright sociable. From what I saw of him, I figured him to be a right, decent sort. I would liked to have shared a pot of coffee with him.
There's nothing wrong with asking for peace and forgiveness between the various peoples. We should keep in mind (involving ourselves also), that even God only forgives those who ask for it !
As far as salvation being open to the Imams (unless they convert)..the pope was just wrong (IMO). He should refer back to our standard before making pronouncements:
6) Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. (John 14:6)
