Has India started to move into another league?

In light of President Bush's visit to India a few days ago and the new nuclear deal inked, lets highlight some far-reaching consequences that could play out. From International Herald TribuneAndy Mukherjee's article:

If India can use the accord to overcome its energy crisis, there is a lot that its fast-growing economy can buy from the rest of the world. That will be the ultimate economic prize for the global economy if it accepts India as a de facto nuclear-weapons state. 

Whether the prize is worth the risk of "tempting" states without nuclear weapons to give up their "self-restraint," as Talbott puts it, is for Congress to decide.
The same concerns being raised in Washington about doing a deal with India were debated in 1985 about the wisdom of sharing fissile technology and equipment with China.
Although it took 13 years to complete the U.S.-China nuclear cooperation agreement - it had been submitted to Congress when Ronald Reagan was president and it was implemented in 1998, under Bill Clinton - the deal went through. Reservations in the United States about China assisting the nuclear-weapons programs of Pakistan and Iran did not scuttle the agreement.
With no skeletons in India's nuclear closet, the United States may find it a lot easier to end the Indian blackout.

Has India started to move into another league, slowly and tentatively? Perhaps, yes.  I do not think the nuclear agreement deal itself is the silver bullet but could be chain reaction to important developments in Asia. More importantly, change in perception.
