I humbly suggest all my Catholic friends, especially my Catholic Neocon friends, read the following books. You will find them of great interest. You should also watch Andrew Bacevich's video. These books are more than just discussion about Iraq, but are a clear articulation on what the Church teaches on Just War. The diverse collection of various authors is the best I have ever found in any books on Just War. Regardless of where your opinions fall on this topic, these books are very much worth checking out.
