One last thing before Lani cuts the Ethernet cable. I know I'm probably the only person who actually reads books that get recommended in coversations like this but I would like to strongly recommend anyone interested in thinking about the moral dimensions of war to read
Just and Unjust Wars: A Moral Argument with Historical Illustrations by Michael Walzer. It is perhaps* the most impactful book I've ever read (not that everything I've said in this thread in echoed in there; it's not and I'm sure Walzer would be appalled at times). It was written originally in 1977 and has been revised since, with the most recent in 2000. Obviously it doesn't include any direct comment on the current situation.
*It has to compete for that title with
Cadillac Desert: The American West and Its Disappearing Water.
