First i will address Russian S400 saga and the possible future of Pak-Russo relations.......
The tiny puny Island nation of Britain made the giant bomber called Avro Vulcan with 98% components made in Britain.
136 of these were built mainly for long range bombing missions and as a means of delivering Nuclear Payload to USSR in case of a Nuclear conflict.
The British only had 200 Megatons of Nuclear strike power . The Soviets had Gigatons not Megatons. A few Thousand Megatons of Nuclear strike power.
The British were aware of that and told their Vulcan pilots not to return to UK after dropping Hydrogen bombs on Soviet cities. The Soviet retaliatory strike would be so massive that by the times the Vulcans return to Britain the tiny island would be converted into Smouldering radioactive charcoal uninhabitable for the next thousand years.
The Pilots of British Nuclear strike force were taught Mongolian language and given coordinates of Mongolian prairies where they could possibly land their jets after dropping bombs on Soviet Union, and start living in Mongolia.
Yet the undoing of the scary Soviet Giant came down by the hand of another supposedly insignificant nation, Pakistan.
A young Soviet Spy was observing it all ,same as his other colleagues. This new Intelligence force they came across was working in ways they never saw before. The keen and talented Soviet Spy was called "Vladimir Putin".
Today he is the president of Russia and remembers all that. He is still wary of Pakistan and still can't trust Pakistan .
R u getting my point? we need to understand the magnitude and entire dynamics of any relationship past present and future, all involved......by having a full understanding of grand chess board and of the great game being played in the world today......Thats why i said yr too focused on mee india only but neglecting the entire regional politics.
This is how Russia or Putin's Russia is thinking......
Now by putting S400 sales to this picture, this lack of trust thing that i mentioned earlier just swells. Now in such a context the future of Pak-Russo relations does seem very limited, as this sends a clear message to Pakistan from Russia. This below video will explain this better.....
Now keeping in view the above, now lets talk abt this pipeline in this context and scenario. After this S400 move india has limited pakistan's defence and political relationship with Pakistan, and through this pipeline they wish to future limit or finnish this relationship by ''going for the kill''
This video above further reinforces yr points much more then mine if u think in that way........But what im telling u here is about how should we maneuver now and how should we decide the future course of this relationship......whatever i have been writing till now is being written in that context by keeping all of the things i mentioned above and what u have already written in the back of my mind (its not like we both r too far off thinking wise).
If india does really manages to turn this pipeline concept into reality by going undersea and making it go till their gujrat coast, let them go on...........It will be far too expansive for even india to build it and then sustain it....even the coastal ports of india arnt suitable to even build a deep sea port because of the large concentration of under sea rocks so much so that the large container ship have to park themselves 45 km off the port of mumbai because they cant go further......But there is no such problem in Pakistani coasts, its just as smooth under sea as it can get......Thats why deep sea port like Gwadar is being build in Pakistan not india or iran. Which by 2045 will have a capacity of 400 million metric tons only second to Shanghai port's 500 million metric tons capacity, making her the second largest port of any kind in the world.
Now keeping that in mind, i believe that let them build this undersea pipeline, first they will waste 100s of billions dollars building it, then if they r still able to build it which i highly doubt they can with their mere 2 trillion economy which is already slowing down, then i highly highly doubt they will be able to sustain it, because all we have to do is send some frogmen to puncture it in multiple places time to time if they do manage to build it so close to our EEZ.....The expenses of its long term maintenance, even the expanses they will have to bear just to merely subsidise this gas to be send to indian homes and economy, or industry will be mammoth.......Resulting in further slowing down their already sterilized and stagnated economy and with a constant and permanent burden on their reserves in subsidising this forever.......Overall it will mean that india will get only a short term gain from this put will have a white elephant in the long run. Because make no mistake iranis, russians or even omanis will not be selling this gas for free either, they will be selling them on profit ie expansively...because irani economic situation is there for everybody to see and so is Russian as explained in that video, omani maybe fine for now but will not be forever too.
They will have to run to Pakistan just to keep their expanses under their means....as they say AAMDANI ATHANNI KHARCHA PURAIYA!!!!!
U need to keep in mind the mentality of this Hindu Banya too......they will eventually give in. Hindu banya is just ziddi like a spoiled kid......Thats why i said i will be the happiest man on earth if they succeed in building this project of this great magnitude.
Now im focussing on the point number 2 what u made at the end of yr post.
Regarding Russia and China, well China has already shown interest in taking the existing gas pipeline of IPI into China from pakistan rout along CPEC when india backed out......Well maybe that gas wont come from Russian stock of Fars field but atleast Russia is building that pipeline (north south) in pakistan isnt it(forget abt that undersea or off shore pipeline, let them build it) So there is something for them too in it rather then having nothing at all isnt it? Afterall as explained earlier these relation with Russia now will always remain limited.
Pakistan herself is a country of 220 million people, and Russia is of mere 140 million, it will definitely be in their interests to cater this giant market of Pakistan too in her energy needs......independently of india. Because if not, then the way i see it, its their own loss not really ours!
