Thank you for sharing these songs and your experiences. I'm sure it can't have been easy.

I didn't know the Waterboys song. You may be aware that it quotes the Russian folksong Meadowlands ( https://youtu.be/XoXsxccZi3M ).

Here are three more that protest against the horrors of war without resorting to shallow platitudes or patriotic jingoism or simplistic shock tactics:

* The Kinks, "Some Mother's Son" (reminiscent of Thomas Hardy's poem "The Man He Killed": https://youtu.be/seMc_UaE3FQ

* Mono, "Little Boy" No words necessary to depict the horror of nuclear war: https://youtu.be/gAG8qIWrtbI

* An entire album, "Balaklava" by Pearls Before Swine. Nothing shocking or strident in the songs per se. The album shows how we enable warfare by ignoring or justifying its horrors during peacetime. https://youtu.be/RWZSo01v_uQ
