Clause 103-b-4 states "Secure India’s full and active participation in United States efforts to dissuade, isolate, and, if necessary, Sanction and contain Iran for its efforts to acquire weapons of mass destruction, including a nuclear weapons capability and the capability to enrich uranium or reprocess nuclear fuel, and the means to deliver weapons of mass destruction."
The clause is pro-India. We cannot have another nuclear neighbor. China & Pakistan is bad enough.
This clause is the reason why the Left and BSP term the agreement as anti-Muslim. The question is why the BJP joins them in opposing the deal - for a few Muslim votes?
