Hypocrisy? That word literally translates to say one thing and do another. Lets see. China told India that it will let it join the NSG and then when it came time at the table voted against it. No, that did not happen. In the other instance. One of the major rules of all countries currently participating in the NSG have a clear rule of is being a signatory of the NPT. The US being one of the main proposers of that rule. Today it was the one looking the other way of that said rule. That my kind sir is what Hypocrisy means. Now if someone was smart and see what the US did here it would be all but obvious. In the past when the US needed something to happen it would change the rules first and then it would be all legal. Pushing India to hit the rule wall was just more fuel to the conspiracy theorist.
Hypocrisy is also when the Chinese ask India to adhere to NPT but they themselves violated by helping Pakistan in nuclear know how.
And america making way for India to be in NSG isn't about hypocrisy, but about reality.
The fathers of nuclear stuff - UK,France,US,Germany and Russia-all have favored India's membership. If the world knows anything about nuclear stuff, it is because of these nations, and the ones who are objecting to India, are the ones who merely followed the foot steps of these nations.
When all the fathers of nuclear stuff are supporting India's membership, it is only a matter of time before India becomes a member of NSG, rest of the opposition are bunch of jokers (except china).
India has come a long way in scientific and technological growth, it will only keep moving forward from here. There are multi billion dollar worth industrial houses in India which are now capable of designing and manufacturing extremely complex sub systems for nuclear stuff. Pakistan is light years behind India in Industrial and scientific fields...
The west recognized India's growth in industrial and scientific fields, only then it realized that it was better to put India under NSG guidelines than to not, and hence the NSG waiver. The NSG waiver didn't come for free nor it was about giving exotic nuclear stuff to India, rather it was about to bring unrestricted India under restrictions and demand strict standards of control on stuff. By securing NSG waiver for India, the US ensured that potential new global power will be an ally for US in the future.
The US didn't bend the rules for India at NSG waiver, rather it was India's growth and rise in economic, scientific and industrial fields that changed the minds of policy makers in the west to make India it's ally.
If India was in Pakistan's position-- with no economic power, with almost non-existent scientific and technological sectors--Americans would have never bothered to offer NSG waiver to India. And that is why they are not offering any such sort of NSG waiver to Pakistan right now.
And the talk of "India and Pakistan becoming NSG members simultaneously" is a joke to begin with.... it is only a matter of time before India becomes member of NSG
