I think that politicians today should use Augustine’s Just War theory as a base line for determining when to take military action. Romans 12:18 tells us that we should live at peace with everyone if at all possible, however, this is not always achievable. I think this is the same idea as Augustine saying that a Christian’s default should be pacifism. We should not seek out a fight for no reason. But we are also told in Romans 13:1-4 that the government does not bear the sword for no reason, but it does bear the sword, and God has given them the authority to use it when it is necessary to carry out justice. This applies to Augustine’s point that says that if faced with a great wrong that could only be stopped by violence, it would be a great sin to sit back and not take action. Therefore, military action may be used for protection, but not for gain, or just for the sake of fighting.
