This book reveals how Putin and the Russian Orthodox Church have been working hand in hand lately, with Russian Orthodox priests taking over the role formerly held by political officers during the Communist period. They keep an eye on the spiritual purity of the troops, glorify the military, ensure the soldiers’ reliability during combat—and even bless nuclear weapons, sprinkling them with holy water.

The ongoing nuclear power plant disaster in Japan has once again pushed the topic of radiation safety into the public consciousness, while also reminding us that the public continues to doubt government and nuclear industry information on safety and the effects of radiation. Part of this wariness stems from the fact that people cannot detect radiation using their own senses, which creates a dread of the unknown. People are also very aware that the effects of radiation are cumulative and may not appear for many years, so the outcome of a disaster like Fukushima is not easy to predict.

While chemical and nuclear weapons treaties have systems to verify compliance, the Biological Weapons Convention (BWC), a global pact banning bioweapons, does not.

For decades now, India has obstinately resisted the idea of joining the Nuclear Non-Proliferation Treaty (NPT), claiming that the treaty is both flawed and discriminatory. Thus, India, a country with a nuclear weapons arsenal, has long stood outside of the nonproliferation regime. Yet recent government statements seem to indicate that New Delhi is rethinking its stance on the treaty--a very timely discussion, given the upcoming 2010 NPT Review Conference, at which reforming the treaty to reflect current security considerations is likely to be a topic of deliberation.
