I think that’s the kind of credit Beijing would be a happy not to take.Shows that Beijing needs work on its branding, with the guys shouting "death to USA and Israel" when the UAV was actually produced in China. Stomping on that air-to-ground missile probably isn't a great idea.
I did find it amusing that America and Israel are getting the ‘blame’ when rebels are getting hit by Chinese made weapons.
But then that is a benefit of China’s non-interference policy. China just sells stuff, it doesn’t involve itself in what people do with those things. As such, people have less beef with China even despite all the focused propaganda of the western media trying to make China out as worse than the original European slavers and colonisers.
