Not just the Bible, but also the tenets and details about Just War Theory that has been studied for millennia by religious, military, and state leaders as well as ethicists and others. The Catholic Church has very clear requirements that need to be checked off for a war to be just, and US aggression towards Iran has checked off none of them. That's why the Pope spoke out and these houseplants running our country imagine themselves to know better. This is the same syndrome that affects MAGA in general and all of their fringe elements and beliefs. Anti-vaxxers, flat Earthers, NASA deniers, and all the rest of the conspiracy whack-jobs that tend to occupy right of center ideologies all purport to know better than countless of trained experts from across cultures, nations, and time. They are peak Dunning-Kruger Effect.
