The recent weeks have seen a revival of the dormant India-US nuclear deal, signed in 2008.

It took six long years for the two countries to declare that issues relating to the deal have been resolved which was claimed as a breakthrough.

While one could feel good at finding a solution "culminating towards commercial operation consistent with our laws and international legal obligations", as stated by Prime Minister Narendra Modi, without further details, no clear conclusions can be drawn.

The statements by Prime Minister Modi and US President Barack Obama made during their press conference support this assessment.

So the question now is: How soon will the 'breakthrough' lead to accelerated addition of nuclear capacity, thereby addressing the issues of climate change and energy security.

Assuming the answer is sooner than later, more questions arise, which need to be addressed.
