This book was written by dozens of authors who, in the media and online publications, strive to show that qualitatively new types of weapons have been created and really threaten humanity. Someone, not without humor, called some of them “non-lethal.” Sergei Ionin proposes a new term - “parallel weapons”, that is, weapons that are not considered at international conferences and summits, are not recorded in documents on the limitation of various weapons, but these are weapons that, perhaps, will be more terrible than those already existing. The publication is of interest for the widest range of readers: the author’s acute question: with what and how will they kill us in the 21st century? - will not leave anyone indifferent.
