You are right LF Sir, India can positively play as Mediator between Iran and The USA,also there may be a another patch up with the relation with arrest of an US-Iranian journalist by Iran and subsequently accusing her for 'Spying' , however , with coming back to the point, I'll say that if India successfully can mediate between the USA and Iran on opening up of a possible Nato supply route,as the route along with the port Chahbahar developed with Indian Assistance, not only the Iran and also the USA benefited but also India immensely.
Hi Pintu
I fill in where I can
If positive there can be out come:
1. Iran coming out of the 'Rough Nation' status.
* This is difficult most or a good portion of the worlds terrorism comes or is supported by Iran. I'll admit I may be a little closed minded when it comes to Iran. Americans have directly been killed by their support and many locations around the world.
2. Iran having extract an assurance of stopping support of Jundallah by the USA, and cease of activity of Jundallah and peaceful settlement of problem arised in Sistan and Baluchistan, with staying of Sistan-Baluchistan province as an integral part of Iran, and the province becomes a developed one.
* I don't know all the words you mention but getting any trusted assurance from Iran would be difficult to swallow. There government basically hates Americans and fuel many others to do the same.
3. Vice- versa , Iran , India helping Coalition Forces in Afghanistan , as Taliban are common enemy of both Iran , India and also USA(if good taliban / bad taliban theory is out of the USA's mind).
* I don't believe that myself I feel that it will be found out that Iran or groups in Iran have been playing both side, what makes them any different that Pakistan. I feel in time direct links between Iran and the Taliban will be found.
4. Positive settlement of Iran's nuclear issue.
* Not while there President is saying the US and Israel should be wipe off the plant and mask covered people shooting off AK-47s in the street while burning American flags and chanting kill Americans.
5. Development excellently in Indo-Iran relation and anti-Indian propaganda in some Iranian media be stopped.
* That's an Indian-Iranian issue and having strong public ties with Iran won't help India.
6. Hostility between Israel and Iran deescalates, that is using of rhetoric at least stops.
* A very wishful dream Iran doesn't think Israel deserves to be a country and directly support Hamas and others that kill Jewish children and so on, just don't see it happening.
7. More contracts in Iran awarded to Indian firms, strong relation to Iran, and possible energy co operation between them.
* Again a India-Iranian thing
8. More Importantly minimise China's activity there, with Iran stops importing Chinese Arms, and Chinese dream of having military base in Iran tatters.
* Difficult to stop China imports large amounts of Iranian oil not sure about natural gas. China will trade weapons for oil and Chinese weapons are cheaper then western ones overall, so don't know if the weapons part would really stop. Americans see China much less an enemy as Iran, we don't trust China but there not Iran. I also see China behind a lot more going on in the world but that's another thread.
However all the out comes, I wrote here are just a possibility , if future indicates that India moving to talk with Iran for using the Chahbahar route, and only if Nato, and the USA affirms positively about opening of a new route through Iran and consider giving Iran 'concessions' , for allowing its soil for that, which I wrote. I can be wrong in my assumptions.
