India is the clear winner in this deal, and I don't think the United States gets anything out of this deal (except for mango parfaits, LOL!) Energy prices will only go down a whisker in result of their inauguration into the "Nuclear Club".
Though it won't increase the tensions among those who have had to endure higher costs for winter heating and such, I fear tensions with others in the international community will grow out of this, where Iran especially will wonder why India seems to wear a halo in being trusted on nuclear technology, but with them, all hell breaks loose. Iran is going to use the India issue as political leverage in why they don't have the right to nuclear technology, North Korea will too, China will be part of the conflict, and meanwhile I've been predicting eventually Iraq will try to rush toward nuclear development in following their lead.
The US-India relationship is certainly stronger after this decision, but elsewhere relationships are uncertain or shaky, and in terms of reversing the trends of nuclear proliferation in the world, this is one step backward.
