Evidently you have never heard about “Just War.”
Ecclesiastes 3: “A time for peace and a time for war.”
Yeah, I’ve heard of it. I just seem to recall the Catholic Church generally opposing most of our military operations. I’m not an expert on it (and could be wrong), but it seems like they mostly come out opposed to us.
I find that all too often the Catholic Church is simply on the left of many or even most issues. They are socially conservative on abortion and contraception, but when it comes to immigration, death penalty, bloated social programs, gun control, military operations, etc, they always seem to be on the left.
