How in the changing geopolitical scenario CTBT (comprehensive nuclear test ban treaty) and NPT (Nuclear non proliferation treaty) are unable to avoid nuclear warfare? What are the global checks to nuclear safety and India's stand on it?

Hint:

• Increasing tussle in the Asia, between the nuclear countries like Pakistan, India and China
• Pakistan losing control of the nuclear weapon as a result of unstable polity and governance in the hands of extremist forces
• Growing threat of weapons falling in the hands of such jihadi forces like ISIS, Al-Qaeda etc

India’s approach
India’s is neither a signatory to Nuclear Non-proliferation treaty (NPT) nor to the CTBT because of its discriminatory nature in its present format as is advantageous to the nuclear weapon holders.
