Lets get a few facts correct
Nuclear Deal:
India has got a permanent waiver from NSG. China is helping Pak get this "1-time" waiver for 2 civilian nuclear reactors.
Fuel exports for current reactors and planned reactors (Such as the Chashma ones) would be covered under the reactor agreement from China.
NSG approval would only be necessary if Pakistan wanted to import fuel from any of the current NSG members who did not agree with the Sino-Pak position that the export of the reactors was legitimate & remember Pakistan offered global nuclear fuel services & you were all thinking that Pakistan is joking
Pakistan has in the past proliferated nuclear tech to Middle East/West Asia/Arab World, which is not a problem area for us but it is for the West. We have to wait and watch how the things go as our say in this whole matter is limited, if we create a raucous it will backfire, if we keep silent it will show us in a poor light. It is time that we show our statesmanship not petty-ship.
the proliferation record of Pakistan is outta light now, Pakistan was there in Nuclear Security Summit & US on record said that past is past, time to move on & they were ready to make exceptions because their legitimate concern was/is IRAN, Indians can scream as much as they can about 'proliferation' that ain't making any difference
US:
US needs Pakistan establishment to be onboard so that it can swiftly, and if possible graciously, exist the cesspool that is Afghanistan. Milking US for military goodies and a few billion per year and at the same time destabilizing your country and the neighbours and permanently putting the brakes on your economy is not a smart thing.
US is in a mess in Afgh, no one can deny that, the problem of Islamists is mutual, the only difference is that Pak is good at extracting benefits, though at certain points they messed up big time
Iran:
We have financed the Chahabahar port in Iran, building highways linking Iran with Astan, also financing/building railways connecting Iran with CAR/Russia, upgrading their military, training their officers and investing in Iranian gas fields and companies.
Iranians are that fools that they will shun a multi billion Dollar deal with Pakistan just because Indians are investing, haaa
Pakistan - Iran on the other hand have always seen each other suspiciously (state sponsored anti-Shia pogroms, Balochistan, Afghanistan; Zardari being a Shia probably has had something to do with this). In any case the Iran-Pakistan deal is not a financially sound deal. And to make matters worst Iran is currently a pariah state and Pakistan will be paying Iran with money received as aid from US.
ohh my gawd, now thats conspiracy theory,
Zardari been Shia has got something to do, ohhh, will you explain that crap?
Remember that Rigi just got executed & who caught 'em? You have a bad memory
& Again Iranians are such fools that they would not have thought about the 'financial part' of a 7 billion dollar deal, Singh are you all right these days?
