The good part is...we will get lots and lots of fuel....along with other economical cooperation for US and its allies....
Bad Part:- The Security and detterence policy being implemented by India will go to hell....Its clearly mentioned...the enrichment should not be there for accurign nuclear weapons...so from where else we will get efuel to feed our nuclear deterence policy. And mind me....dats the only thing which can make a country work its way...thats the arm of free state...Because of this only...we had sanctions in 1998...we knew...we were not afraid of sanctions...but of the atomic policy is not shown to world...may be in few days...china will take the arunachal pradesh....may be US will not be that much afraid to enter the indian waters...may be pakistan will force to wage another war...as we know....US has good business...and I assure you this will will welcome more and more deals in the future....
WE CAN ONLY GROW IN A PROTECTED AND SECURE ENVIRONMENT...WE DONT WANT TO WAGE A WAR...BUT ALSO WANT NOBODY ELSE TO WAGE A WAR ON INDIA...WHICH NEEDS POLICY...ATOMIC POLICY...
