Well, that's the thing. I think that the current Pope has placed too much hope on appealing to the conscience of the Muslim world - his predecessor St. Pius V took a different position at Lepanto with overwhelming success.
A future Pope may rethink JPII's policy in light of developing events.
Well then I don't know what the answer is. I supported the war 100%, but I would be very unfomfortable with a Pope who advocated military force. That's not what Popes are for.
