Why would Iran be involved with a planeful of citizens from its main buyer of oil and supplier of military technology?
The caliphate or whatever it is when the new Allah comes out of the well, is why. Zealot muslims are always muslim first .
China wants the oil much more than Iran wants to sell it to any particular buyer. When Iran or anyone’s oil hits the market its up for sale to anyone willing to buy it.
Could the Iranians be interested in whatever cargo the plane was carrying? I thought Iran, via Pakistan, as well.
