Chandra Shekhar Jha was India's foreign secretary from 1965 to 1967. In this video segment, Jha explains why India cannot exclude the future possibility of owning nuclear weapons. The key to disarmament, he insists, rests with the nuclear nations that are 'adding to their stockpiles' and 'preparing for war. 'Jha's interview conducted for War and Peace in the Nuclear Age: 'The Haves and Have-Nots' begins with his recollections of his devastating post-war tour of Japan with Prime Minister Jawaharlal Nehru and their shared ideals of disarmament and economic development by harnessing 'Atoms for Peace.' Jha's interview also examines the dilemma of staying the non-nuclear course given regional security concerns: the 1962 Chinese attack on India, followed two years later by China's detonation of its first nuclear bomb, and ongoing tensions with its neighbor Pakistan. While prioritizing the country's economic development over diverting resources to acquire nuclear weapons, Jha rejects the Non-Proliferation Treaty as embodying 'nuclear colonialism' and objects to the preferential treatment granted other threshold states.

"Lines of Force" opens with footage of a dramatic explosion. For most of the piece, the screen is divided, into a triptych at first, and slowly into horizontal and vertical bars. Electronically manipulated footage shows a man walking, a marching band, ferns, cartoons, a window, and a train arriving on a set of tracks. The naturally occurring lines in the array of images presented mirror the electronically created bars and lines that divide the screen. Natural scenes provide a respite from the frantic pace of the images. The music score was created by Bob Snyder. The music mirrors the pace of the work. When images are at their most frantic, sounds like free jazz horns blare forth. More lyrical electronic music mirrors the more peaceful arrays of natural images." Lines of Force' was broadcast along with 'Winter Notebook.' Both works were created by video and sound artist Bob Snyder. New Television Workshop appears to have presented but not produced the works. "Artist's Showcase' was a series designed to showcase video art and experimental work from WGBH. The program ran on Sunday evenings at 11 P.M., from the fall of 1976 through 1982. In the early 1970's, 'Artist's Showcase' was the only consistent broadcast outlet for many of the Workshop productions. Most materials of broadcast quality created at WGBH in the mid-1970's were shown as part of this series. Additionally, earlier video art experiments and segments of related shows, such as 'Mixed Bag' or 'What's Happening Mr. Silver' were broadcast under these auspices. This series was also a broadcast outlet for a handful of works by video artists that were not created at WGBH but only acquired for this purpose. Some compilation reels showing highlights of Workshop activity were also broadcast.

'This short, meditative film is composed of images from ancient Europe -its bridges, roads, statues, and castles -which become transformed in another time and place, the mind of a lost and weary traveler. While the title refers to the vampire legend, the mood of the piece is more that of a love story, mixing loneliness and longing.' Many of the images in Andrew Moore's 'Nosferatu' are superimposed and electronically manipulated. Repeated images of trains coursing through tunnels and individuals walking forward suggest the forward trajectory of the traveler. The pace is accelerated. There is very little credit information. The original score is by Elliott Sokolov. The work was broadcast as a segment of episode 102 (1991) of 'New Television.'

From 1988 to 1993 nuclear physicist Mambillkalathil Govind Kumar Menon was president of the International Council of Scientific Unions, a non-governmental organization long involved in environmental and development issues. He was also India's minister of state for science and technology from 1986 to 1989, and he served in the Parliament from 1990 to 1996. In this video segment, Menon describes the euphoria following World War II when international cooperation on atomic science and technology flourished.In the interview Menon conducted for War and Peace in the Nuclear Age: 'The Haves and Have-Nots,' he offers reflections on the dynamic and visionary nuclear physicist Dr. Homi Bhabha. Dr. Bhabha saw the possibility for the modern development of India in creating programs that would harness the newly emerging technology of nuclear energy. Menon captures the zeal of scientists at the first United Nations Conference on the Peaceful Uses of Atomic Energy. He also defines some basic nuclear processes and principles: how fission works, controlled and uncontrolled chain reactions, and the difference between generating nuclear energy and manufacturing weapons. In 1974, under the prime ministership of Indira Gandhi, India conducted an underground nuclear test. Menon defends what India called a peaceful nuclear explosion as a means to explore enhanced mining techniques and other feats of large-scale underground nuclear engineering. With equal enthusiasm, Menon describes the possibilities of India's space program for expanding telecommunications and gathering data for waterand land-resource management. The global threat, he maintains, is not India but a nuclear exchange between the two superpowers. Paraphrasing Indira Gandhi, Menon concludes, 'What we want is not to make deserts but to make deserts bloom.'
