Only one risk for India is "What will US do if Pak or China conducts NTest?" "How will US help India in that situation?" If US helps India in these situation and if it is mentioned in the deal, then we can go ahead and sign this deal.
Except for the security, I feel, the deal is good.
Talk with US and come to a solution.
Whenever India was speaking abt Terrorism in J&K, US considered it as Freedom fight. But, post 9/11, US is indeed aware of Terrorism. So, govt of India shold negotiate with US and then enter into the deal.
Terms & Conditions of the deal SHOULD BE DEBATED & ANALYZED before signing
