There’s no reason in the Bible to not be at war with Iran, or anybody else.
Have you read the Old Testament? Several genocides done in the name of Yahweh. Not going to defend Hannity, but the Pope was kind of wrong when he said:
God does not bless any conflict. Anyone who is a disciple of Christ, the Prince of Peace, is never on the side of those who once wielded the sword and today drop bombs.
Even Jesus himself said:
34 “Do not think that I have come to bring peace to the earth. I have not come to bring peace, but a sword. 35 For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law. 36 And a person's enemies will be those of his own household.
Matthew 10:34-36
Pretty much exactly the opposite of the Pope's tweet.
Edit:
Lol at people replying to me thinking that I'm somehow defending the Bible or the scum who use it. Just like pointing out that it's all complete nonsense
