The cowardice and hypocrisy are on your side my friend.  You say you believe Jesus would never allow us to fight a war of self-defense, yet you would have the country be armed with deadly weapons.  You don;t have the courage of your convictions.  Small wonder.  Your convictions are highly suspect even to you.  Did Jesus ever counsel us to wage war in self-defense?  No.  But when the right to do that is so plain, and when Scripture itself approves it, Jesus silence should be taken as a ratification of Scripture, rather than a repudiation of it.  Then there is the business of Jesus telling his Apostles to buy swords, and Paul's telling us in Romans that the State has the right to wield the sword (an interpretation of Paul with which Aquinas agrees).  As for turning the other cheek:  Do you not see a distinction between a man slapping you in the face as an insult and a man coming at you with a hatchet?  You read that passage in Matthew unintelligently because you see no difference.
