Pacifist approach has proven in due time to rarely if ever be the correct approach to correct an issue with a Rouge nation or empires throughout history. Just sit back and allow a bunch of extremist continue to stockpile drones and missles, and don’t worry about them developing a nuclear bomb- Defintion of a pacifist approach. Anyone who thinks that is the correct way to go about dealing with Rouge/ Extremist Iran tell Us how that is the best approach.
First, how and why are you equating opposition to targeting civilian infrastructure to being a pacifist. There’s no reason to needlessly make innocent people suffer or die. We’re better than that.
Secondly, if you’re Christian why do you fear? If Iran obtained a nuke, and truly intended to use it, do you not trust in God’s absolute sovereignty? If they used it or didn’t, it wouldn’t be within our control anyway. Your fear is unwarranted, those in Christ have already won, no matter what happens to us in this life. Nothing happens outside of His control and authority. Now if you’re not a believer then I understand your fear.
