The aim of the dissertation is to explain the military-political reasons behind the long-term attempt of the Soviet Union to deploy its units on Czechoslovak territory, as well as the root cause of the military operation against Czechoslovakia which was carried out by the five member armies of the Warsaw Pact. One of the main reasons for this was the military and strategic situation in Central Europe in the 1960's, and also the issue of nuclear weapons and their carriers.
A separate chapter is dedicated to Soviet attempts to deploy its units on Czechoslovak territory prior to Operation Danube. The final chapter deals with the reorganization of the CPA, the establishment of the CGV and the NATO reaction to the change in the strenght of armed forces present on the border of the two Blocs.
