The author processed a shocking twenty-four thousand pages of American government documents, declassified on May 29, 2021 by the American National Security Archive, with which the author has been cooperating for many years. They refer to when American presidents were the first to consider using a nuclear bomb against the USSR and its socialist satellites during international crises. The first case was the so-called Berlin crisis in 1948. The list of targets included objects in the then Czechoslovak Republic, including Prague. Other moments of similar considerations were during the Korean and Vietnam wars, the Suez crisis, the two wars in Lebanon and others until 1975.
The book contains all the secret negotiations about what guarantees of security and independence will be provided to the newly established Ukrainian Republic if it renounces the nuclear weapons deployed on its territory - and at that time Ukraine was the third most powerful nuclear power. The author is also based on personal testimonies, because at that time he lived in Kyiv and was friends with Ukrainian presidents and Foreign Minister Anatoly Zlenko, who informed him in detail about the ongoing negotiations and Ukrainian resistance to such an agreement.
However, the declassified materials also touch on the years 1990 to 1994 and relate to documents and secret negotiations about how the Western powers assured the then Russian presidents Mikhail Gorbachev and Boris Yeltsin that NATO would not expand even an inch towards the east and ensure the equal inclusion of the then Russian Federation to European structures, including an offer for membership in the North Atlantic Treaty.
