That is well said ,but this time this deal will hurt Arabs as well as Israel ,Reasons Why
1. Iran dependency mainly on oil and other derived products ,Imagine Indian trade thru Iran it will boost its economy on the same principles it will do for Pak with Chinese (you do the maths)
2. Iran conventional wisdom suggests that Iran will put more focused on its military might against Arab as well as Israel (Funding will be generated thru additional growth in GDP Current estimates are 2.5% of GDP) .Now there are only two possibilities either this deal is Hoax and result in no fundamental uplift in Iran economics or 2.5% constant and if there is additional 1% rise in GDP thru additional trade as speculated by many this additional (11 Billion $ will result in more) .Considering IRan defence forces are concentric around GCC ,ISrael ) regarding Merits or demerits there is no such thing in this world ,Sooner or later India has to pay (For relationship with US in cold war ,US supplied all topnotch weaponry to Pak which was arch rival to India ) Today US on the expense of India is even not releasing funds for Pak to fight there war .
