This shit is inevitable but damn am I not looking forward to robot genocide. It'll be so much easier if all you need is some money and a few distant operators. International law won't do shit when there's money on the line.
Robot v. robot "conventional" wars won't be much better, either. Without human casualties there's not really any consequences or reason for any party to capitulate. So either you have to completely starve your opponent of resources or start targeting civilians. The latter being way more effective and cheaper.
