Sort of a broad question, so let me break it down:
1. Should war be avoided at all costs until everything else has been tried, or if fighting a war will gain you a victory, should you resort first to that?
2. It is well known about the service histories, or lack thereof, of several prominent Government Officials... Bush, Cheney, Rumsfeld, etc etc. Do you think that a government official would be more willing to fight or take part in a war if they actually experienced the same type of combat as a regular soldier being sent in? (Basically, I'm attempting to figure out why people who've actually experienced war seem so much more likely not to support a future war upon their return).
3. When is war justified?
Anything else you wish to add or address, by all means. The questions are just to stimulate a debate and need not be restricted to just those topics on war.
Take care all.
