You're not wrong, but the US/UK get the blame when client nations use weapons sold to them (see: Saudi Arabia). The Chinese shouldn't get a free pass for selling weapons into the Middle East with scant regard for how they're used either.

Also, from the Graun link in my parent post:

> the US remains unwilling to allow countries in the conflict-torn Middle East to buy its Reaper drones.

There is a massive difference between bombing conducted by a country and bombing conducted by another country using the country's weapons.

Not to anyone on the receiving end.
