An American Think Tank has claimed that Pakistan is now entering into a new era indicating the capacity to increase weapon-grade plutonium. This became possible after Pakistan’s fourth heavy water reactor at Khushab appears to be operational. David Albright and Serena Kelleher-Vergantini of the Institute for Science and International Security (ISIS) said in their report that satellite images have indicated that external construction of the reactor is complete. There is every indication that Pakistan is increasing its nuclear arsenal at greater speed than any other country in the world. Reports show that Pakistan now owns more atomic bombs than India.
