Looking for an animated anti war short from years ago


I wanted to show a new friend an animation I remember from years ago. It was an anti war anti US animation that was very viceral. I remember an ocean of blood.

It was pretty popular but I can’t find it any more. Not really sure the words to search and was hoping someone here might remember it.

Don’t really want to incite debate just remember it being a powerful example of expressing a point of view
