Terry - I am the first person to admit that I know nothing about war, or what it personally costs the people who fight (or those who decide not to fight). I haven't been in either situation, nor had to worry about my children in such a situation yet.
Jesus seemed silent on the subject of protecting loved ones. I'm not sure that he was. I may simply not be understanding how to apply his teachings to these situations.
However...
One would not be very loving to his wife and daughter (both also included in neighbors) if he stood by and allowed them to be raped or murdered. In another sense, if I were that wife/daughter, I would want someone to come to my defense. (apply that with the golden rule - if I would hope someone would come to my defense, then I would hope that I would also come to someone else's defense)
And finally - Love covers over a multitude of sins. Shedding blood might be a sin. But standing by and watching innocent blood be spilled might even be an even bigger sin. I think this is a personal decision everyone must make, and that none of us has the right to judge that decision. But defending an innocent person is not the same as warring for profit or power.
Again, I'm not the authority on this, and Jesus could also have been preaching pacifism because we would be taken care of in the after life. That takes a tremendous amount of faith, though.
On a personal note, Terry - I've said it before, but I think you are a sincere and caring individual. Just the fact that you live with that on your conscience says this to me. I just hope you realize that YOU are not responsible for that war. YOU did not get anyone killed in your stead. You refused to go to war because you believed it was wrong... and I'm assuming you believed so because you would have had to kill anyone, which goes against what you were taught from the bible.
My point is, from the bit I've learned about you, your conscience would have been hurting either way. You didn't get off scott-free, either. You went to prison, and obviously suffered there as well. Standing up for what you believed was right, no matter the consequences, took strength.
