Presently 35% of Plutonium is used to produce Atomic Bombs. After signing the Agreement, we will be allowed to use only 10%. Who are those to restrict the usage of our natural resource ? That is though you are capable of cooking & eating 10 idlis as your breakfast, you are allowed only 3 idlis henceforth. How can it be? Why should we accept this?
THORIUM
As told by Dr.APJ, we have abundant Thorium. In fact we are the 2nd largest producer of Thorium next only to Australia. India has to explore this further for producing power. For your information, in South India - particularly around Kanyakumari, the availability of Thorium is abundant.
INDIA-IRAN-CHINA
USA does not like the amicable relationship between India-Iran and also India-China. If India-China relationship gets stronger, then both these can rule the Eastern Part of the Globe which USA wants to break as per their divide & rule.
By signing this agreement, USA wants India to depend on it for producing power which is going to be a crucial factor in future. There is a talk of bringing Natural Gas from Iran to India with a big pipeline project. USA doesn't like this proposal.
Atomic Power Technology
Whether power is produced or Bomb is produced, using Atomic power without spoiling the infrastructure and without allowing the radiation is always under threat. Moreover preserving the wastes coming out of Atomic Power Plants is expensive & unsafe.
