Chinese attack drones are almost as good as US drones, and much cheaper, so many countries are buying them.

A drone, used as a weapon of war, is not inherently morally worse than an artillery piece or a ground-attack plane that could do the same job. I would not criticize Nigeria for using drones in battle against Boko Haram or Iraq for using them against PISSI. (Turkey's tyrant started the fighting with the Kurds in order to get more votes, so he has no justification in that fighting no matter what weapons are used.)

What makes drones specially bad is their use for assassinations, away from battlefields.
