Oh God I just read about this like a week ago lmfao look if you ever decide to start a war with any animal other than a group of humans you should definitely not choose a bird species. Just look into a birds eyes once and you know they have zero give. I was at an emu farm back when I was ten, an emu jogged at me from the other end of the enclosure and I was on the other side but it fart darted at me and locked eyes with me when it reached the fence. It was telling something and I think what it was saying was, "if I could get you, I'd obliterate you" and I was terrified. Only other animal that ever gave me that energy was a llama and it spit a loogie in my uncle's eye.
