Pope Says "No" to Religious Wars

The pope is publishing his second of three books on Jesus. Included in this volume are some interesting points that are stirring up a fair bit of discussion (particularly his exoneration of the Jews). More interesting to me, seems to be that the pope,

also insists that Jesus never advocated violent revolution, as some liberation theologians have suggested, saying violence was not His way no matter how valid the motivation.

I wonder, very genuinely, whether or not he would include in this the various wars which have been fought by or approved by popes in the past. I may need to purchase the book myself to satiate my curiosity.
