the jews are not in hell because they killed jesus. the only thing that can damn you to hell is your dying w/ out accepting Christ as your savior. God appointed Jesus to die for us as in all men. He was going to be sacrificed either way so the Jews didnt nessesarily do anything that wasnt supposed to happen anyway. all of the apostles were jews. jesus was a jew. there are jewish believers. there are iraqi beleivers.
and we arent commiting a state sponsored genocide in iraq so you cant compare us to nazis. its funny how america spends billions of dollars to avoid civilian casualties with precision weapons wich is an impossibility in war and every one throws out numbers about the civilians we kill. what about the terrorist attacks which are purposely aimed at civilians? I honestly cannot think of any war fought where the countries involved took as many precautions as we do to avoid killing civilians.
and to answer your main question i dont think war is a sin. thou shall not commit murder is not the same thing as killing someone in a war. The word used in hebrew means killing in more of a covetous sense like if i killed you cause i wanted your wife and had to get you out of the way. Killing in wars, at least biblically is not viewed as a sin. that being said i am not naive enough to think there arent servicemen doing evil things that are against the geneva convention that happens in every war as well. but i dont think it is a government sponsored policy it is just an individual doin what he wants cause he is in a postion where he can.
your whole logic fails. nazis supported christianity so it must be bad. nazis drove volkswagens are those evil?..obviously nazis didnt follow the bible or he wouldnt have been trying to destroy Gods chosen...
ignorance of what is not an excuse?
