Not For Disclosure (3, 2026) | Jonathan Caplan

DISCOVER THE SHOCKING TRUTH THE U.S. GOVERNMENT DOES NOT WANT TO REVEAL. THE REAL 'DISCLOSURE DAY'. From Jonathan Caplan KC, one of the UK's most respected barristers and a leading researcher of Unidentified Anomalous Phenomena (UAPs), Not for Disclosure is the eye-opening exposé on the greatest cover-up in human history. THE INSTANT SUNDAY TIMES BESTSELLER ‘One of the greatest legal minds in the world’ Daily Mail ‘The most persuasive defence yet of the cover-up theory’ Spectator ‘ Sceptics like me have no choice but to read this and decide if we ought to think again’ Jeffrey Archer ‘ It’s made me realize that we’re not alone . . . It’s impossible not to be convinced ’ Annabel Croft ‘Ground truth has been sorely lacking in this debate . . . this new book may open up the true research the world is hoping to see ’ Jacques Vallee When former US intelligence officer David Grusch testified under oath to Congress in 2023 that the United States possessed crashed non-human craft, global attention shifted overnight. But the full story has been kept from the public. Until now. For over fifty years, Jonathan Caplan KC has gathered extraordinary testimony from scientists, intelligence officers, politicians and military insiders across the world – assembling what may be the most comprehensive body of evidence yet on the existence of UAPs (previously known as UFOs). Now in Not For Disclosure , Caplan reveals the truth behind a reality long denied, uncovering a pattern of secrecy stretching from covert Cold War programmes to alleged presidential briefings and clandestine recovery operations. He also presents significant material relating to President John F. Kennedy, secret meetings involving President Truman and Secretary Forrestal, and previously unpublished documents connected to the mysterious 'Majestic 12' group. Drawing on never-before-seen declassified documents, eyewitness testimony and insider claims, as well as sightings, encounters and abductions, Caplan pieces together a compelling account of the UAP phenomenon and the allegations of official secrecy that have surrounded it for decades. Some who came close to the truth, Caplan suggests, paid the ultimate price. Travelling across the United States and beyond in pursuit of answers, Caplan has spent decades meeting key figures connected to the phenomenon. The result is a detailed, up-to-date and thought-provoking examination of one of the most controversial subjects of our time. Meticulously researched, utterly gripping and impossible to ignore, Not For Disclosure is an essential read for anyone interested in UAPs and UFOs, presenting the most comprehensive case yet that the greatest mystery may not be the phenomenon itself, but the effort to conceal it.
