Computer System Security

The threat from extraterrestrials is not Them, it's Us. In this provocative exploration of what we know of the search for intelligent life in the universe, Alexander Wendt explains why, despite the common assumption that discovering a non-human intelligence in our solar system would bring humanity together, there is a real chance that--even without direct contact--it could cause states and the international system to implode in chaos and violence instead. In 2021, the Pentagon announced that UFOs, now Unidentified Anomalous Phenomena (UAP), are not only real, but a potential threat to national security. The Pentagon did not say who the threat was from, what exactly the threat was, nor did it mention extraterrestrials (ETs). Yet this finding raises several existential questions. How would human society react to the discovery that we are not alone in our solar system? Would the discovery of ETs locally unify humanity under a world state, or would disagreements on how to respond to an ali

This book shows how North Korea's nuclear programme is central to Kim Jong-un's strategy for survival and leverage, tracing its roots to the origins of the North Korean state and the evolution of its security policies under Kim Jong-il. It analyses how, upon assuming power, Kim rapidly accelerated nuclear weapons development, culminating in advanced missile tests and a declared nuclear deterrent. This programme plays a key role in promoting regime legitimacy and national security and is designed to deter foreign intervention, especially from the US and South Korea. Diplomatically, Kim has leveraged nuclear capabilities to gain international attention, engaging in high-profile summits with leaders like Donald Trump, while never seriously compromising on disarmament.North Korea under Kim Jong-un also examines how, domestically, Kim maintains elite loyalty through a tightly controlled patronage system -- distributing privileges, purging potential rivals, and exerting strict control over t

A richly detailed collection of transcripts of Henry Kissinger's secretly recorded phone conversations from his time in the Nixon administration that touch on every important issue of Kissinger's day and provide a sweeping view of his era. Henry Kissinger is unquestionably one of the most consequential foreign policy makers in American history. A remarkably influential academic during his long tenure at Harvard, Kissinger became Richard Nixon's National Security Advisor in 1969 and Secretary of State in 1973. Like Nixon, Kissinger left a trail of secretly recorded evidence in his wake. Kissinger began taping in 1969, two years before Nixon did in 1971, and he continued taping for over three years after Nixon's recording system was dismantled in 1973. In The Kissinger Tapes, Tom Wells draws on his expertise in the Nixon era to provide carefully selected, edited, and annotated transcripts of Kissinger's phone conversations, which chronologically highlight the most momentous crises and co
