It’s mostly a joke but it did result in jobs and money being dispersed among poor farmers in rural Australia with zero casualties (human) and minimal emu casualties.
Plus Emus won so, for the Emus, this is perfect because it means they’ve never lost a war and there hasn’t been another one waged against them since! Plus, as Emus are notable for never once using a gun in war, it’s probably good as a case study for pacifist strategists.
