This lines up far more with the reporting I saw about the conflict from none western sources. The area where Iran did not have full control over its airspace, but they certanly had more control over it than anyone else.
It also with the spy planes looks like Israel wants a war agian, but got burned by being the agressor, and so now they are trying to bait Iran into striking in a matter where they have more plausable deniability
I have no doubt the PRC provided subtle aid, but I am hoping for something more overt. Something that would make it obvous this is not the US and Israel vs Iran (and Yeman and Gaza who the western press ignores or says is just Iran)
