My opinion is yes, because I believe that is what Jesus commanded. The Israelites expected a messiah that would lead the Jews to military victory and restore God's Kingdom to the Jews. However, God envisioned a grander Kingdom of Heaven, a "new Jerusalem" (Galatians 4:26, Hebrews 12:22, Revelation 3:12 and 21) that was no attained by force, but by Jesus' precious blood on the cross and his resurrection. Obviously Jesus did not command people to attack one another, so I am not talking about whether it is right to attack without reason. We all agree that such a move is immoral. But how about self defense? Luke 27[Jesus said,] "But I tell you who hear me: Love your enemies, do good to those who hate you, 28bless those who curse you, pray for those who mistreat you. 29If someone strikes you on one cheek, turn to him the other also. If someone takes your cloak, do not stop him from taking your tunic." You cannot justify war out of self defense. I am sure that one can pull out a passage from the Old Testament that says otherwise, but Jesus offered a new covenant that supercedes the old. He even specifically repudiated the idea that retribution is righteous: Matthew 38[Jesus said,] "You have heard that it was said, 'Eye for eye, and tooth for tooth.'[Exodus 21:24] 39But I tell you, Do not resist an evil person." Christians in this country have to stop asking for more war when it so blatantly goes against the commands of our Lord and Savior. I mean, I do not want to be blown up or nuked either, but my security and possessions here on Earth take a back seat to the will of God.
