The Indian government is not in a position of further testing nuclear devices. The government has already signed many treaties of peaceful use of nuclear power. It tried very hard to win the faith of Nuclear Supplier Group (NSG), IAEA, and other countries like Australia, Russia, France, and U.S. by signing the Indo-U.S nuclear deal. India, if it continues testing the nuclear device, might upset this group of nations and may fall under imposed sanctions once again losing trust of the international diplomats.
In between, the good news for the government is the declaration made by the US Secretary of State, Hillary Clinton, who made it clear on July 18, 2009 that the Indo-US nuclear deal is not linked with India signing CTBT.
"No. not at all," Clinton said in an interview to a TV channel when asked if the deal would be held hostage to India signing the CTBT. "I worked very hard for the Indo-US civil nuclear deal. I am very committed to its full implementation," she affirmed.
She in discussions with Indian leadership in New Delhi and explored how India and US can work together to prevent the rogue states to steal and acquire of nuclear material and technology. She is worried about the Pakistani nuclear bomb falling in the wrong hands, as it is not exactly known who controls and runs Pakistan since militants, Army and non-state actors posses more power than the government in that region.
