I understand what you're trying to say, but sarcasm should be used sparingly when discussions get heated. The Iranian (government) has a chip on its shoulder when it comes to Pakistan - it comes across as arrogance driven by a superiority complex. Yes, Pakistan has close ties with the Saudis and the GCC, but Pakistan has remained largely neutral in the Saudi-Iranian conflict.
Given that Pakistan is struggling with both TTP and BLA/BRA terrorist groups in Balochistan, it is rather unfair of the Iranians to jump down Pakistan's throat every time there is an incident on their side of the border. If anything, the Iranians need to realize that it is Afghan support for the BLA/BRA/TTP that is the issue and that they have common cause with Pakistan against Afghanistan on this issue.
