The argument is not that civilians get killed in wars as throw enough ordinance around and even the most careful actions are going to result in civilian deaths, the argument is that the Russians are specifically targeting civilians.
I doubt very much that one can target civilians with drones,or even with another weapon (artillery,aircraft,...).
Unless one can given the proofs that the Kremlin ordered its forces to kill intentionally civilians ,specific civilians, the reality is that the drones used by the Russians are as precise ( better :imprecise ) as the Ukrainian and US drones and that this imprecision is the cause of civilian losses . A drone is nothing more than a missile and if you direct a missile on a target thousands of km away, surrounded by civilians,the result will be collateral damage .
And ,maybe, one should start to compare the precision of the bombs used against cities in and after WW2 and the precision of the drones . I doubt that there is a big difference between both .
The V1 and V2 ,which were used against big targets much to early,were totally imprecise .Some fell on wrong cities. The drones,used against very small targets are not much more precise .They killed persons who were not the targets .
