Don't trust Pakistan. They are attached at the hip to the CCP who has a lot of money invested in Pakistan and supplies them with the bulk of their military assets - most of which have now been proven useless by many recent military engagements. Pakistan is doing Beijing's bidding. Beijing needs the Iranian regime to survive or their whole BRI plan of anchoring in the ME through Iran will be blown to hell - literally. Losing Iran would be another huge blow to Xi's legitimacy - which currently is very shaky.
