This topic was debated back in January/February 2021. We chose it because it represents an intersection of both practical concerns and utilitarian arguments as well as more "moral" arguments about the ethics of robotics and war. Here are some resources from when this topic was debated. Keep in mind that 2021 was three years ago: there is definitely new data and arguments to be explored!
