So it's ok as long as it's their people who are dieing?
I think we all agree that the ideal situation is that no-one dies. Failing that, fewer people dying is better than more people dying, right? If one side replaces all their combat personnel with robots, that would reduce the total number of casualties and be an incremental improvement.
But it may then lead the strategists to authorising tactics that would be unthinkable if they had actual humans on the ground, thus increasing the number of casualties on the opposing side, which would be a bad thing.
Overall, I think that reducing the number of soldiers in warzones (on all sides!) is a good thing and to be encouraged. Ideally, they'd be replaced with nothing, but failing a mass outbreak of sanity I doubt that's likely any time soon. Replacing them with robots has potential pitfalls that may lead to increased deaths. But, overall, it's probably a good thing.
Especially as
robots are unlikely to rape eachother.
