‘With the prospect of a possible tactical nuclear attack by Russia if it loses in the Ukraine war a real possibility, the subject of nuclear terrorism is once again at the top of governments’ national security concerns, especially if Russia were to utilise a terrorist group proxy to carry out such an attack. This important book provides a comprehensive examination of how nuclear terrorism can be prevented through various measures, including an international arms control regime (ACR). The author explains how an ACR is structured, its key characteristics, its strengths, weaknesses, and gaps, and future directions for strengthening it.’
