Just my opinion, but they do "well" against Americans (Russian, whoever else is foolish enough to weigh in) because the war is asymmetric. They have no issue killing civilians or causing any collateral damage. The US must instead try and precisely get them and only them - and while drone mistakes happen (and they might or might not be mistakes), the US largely has to operate under a completely different and restricted rules of engagement compared with their enemy. The enemy instead folds into the civilian population, making the war extremely challenging.
