The military attack on Ukraine failed due to the fact that it was overly secret, writes Deutsche Welle with reference to the report of the British Royal Institute of United Services (RUSI).
Its authors claim that even the Russian military leadership did not know about the intention of attacking a neighboring country.
According to experts, the Kremlin plan suggested that the Russian Federation would invade Ukraine, will occupy it in 10 days and end the annexation of the territories by August, but the Russian troops were tactically not prepared for its implementation.
