Kohl and Kravchuk discuss Ukraine-Russia relations and problems within the newly established Commonwealth of Independent States. They review the prospects for the dismantlement of nuclear and chemical weapons in Ukraine.

In this letter two nuclear scientists from UIPhT described the construction of the nuclear bomb and proposed to start activities in producing of the nuclear arsenal and make these activities secret. Two Ukrainian physicists were first Soviet scientists who revealed the way of producing the nuclear weapon (of course they did not know about the similar inventions of the western scientists which were made at the same time because of secrecy regime).

In this document, leading Soviet scientists criticize the idea of Kharkov physicists to use Uranium in military goals, because they do not believe it is possible to realize nuclear fission in the current practical conditions faced. The Soviet National Committee of Defence received these skeptical assessments in 1941 and decided not to develop the military nuclear program.
