While I don't like the tone of your argument but ignoring that for a moment, let's see your argument.
What exactly is the probability of $200 per barrel. It is understood now that the oil will never even reach $100 ceiling ever again. Shale gas and renewable energy etc. Anyway if it does reach $200 then the whole world is f***** and so will be we. But we will not be affected as much as you guys. You country will see the strongest growth in Petroleum usage in the world till 2040. Last year alone you guys imported around $80 Billion worth of petroleum, and that was at less that $50 per barrel. Now at $200, quadruple that to $320 Billion, you already have a trade deficit of more than $130 Billion. So your foreign reserves will be depleted in a year. As I said we will all be f***** . But again thats not gonna happen.
Also as an Indian friend was trying to explain in another thread to my countrymen regarding Russian relationship with China and Pakistan vis a vis India, that International diplomacy does not work like school playground.
We can work with Iran while still staying at friendly terms with Saudis. We did not take part it their Yemeni debacle, and people were saying that our relationship with them is lost forever. But their armed forces were parading on our republic day, their air force was performing on our independence day, we are still training their forces and yes we are still benefiting from them economically.
You think we can not afford to lose KSA, but KSA also doesn't afford to lose us either. They can't afford to make an enemy out of Pakistan by kicking out our expatriates. They are already at odds with one regional power of muslim countries, do you think they will be foolish enough to make another.
