In a write-up in Nature (5 July 2012), Scott. D. Sagan warns that danger from nuclear weapons is mounting and pleads for global nuclear disarmament as the only sane path, however complex and difficult it is to achieve.
It is interesting to note from the article that 95% of the World’s nuclear weapons are held by USA and Russia (8,000 and 10,000 weapons respectively). Pakistan is projected as possessing 90-110 nuclear weapons in comparison to India’s 60-80 weapons.
Coming October is exactly the 50 th year after the Cuban Missile crisis when USA and the erstwhile Soviet Union were on the brink of a nuclear confrontation. The author also mentions the 1999 Kargil war between India and Pakistan when the two nuclear powers were on the threshold of a major conflagration with a nuclear threat. He emphasizes the important tasks for scientists and engineers in building a global disarmament regime.
