The "Just War Theory"

excerpt:

"The principles of a Just War originated with classical Greek and Roman philosophers like Plato and Cicero proposed by S. Augustine and St. Thomas Aquinas, and made available for everybody by Hugo Grotius... However, it is a "theory", and with it hundreds of bloody wars have occurred in the last 1600 years... and may be it is time to think of a New Way, considering the teachings of the Gospels and the the personal pacifist attitude of Pope John Paul II and many other modern Christian leaders."
