This was reported by a representative of the Ministry of Defense of Ukraine in an interview with Bild
"President of Russia Vladimir Putin consulted for a long time with the Chief of the General Staff of the Russian Federation, Valery Gerasimov, and the Minister of Defense of the aggressor country, Sergey Shoigu, before the invasion and postponed the offensive three times. According to our information, the offensive was last postponed in mid-February. The FSB pushed Gerasimov to invade. The Russians were sure that they had conducted sufficient preparation because they invested huge resources in it," said Vadym Skibitsky
At the same time, the General Staff of the Russian Federation seriously miscalculated in assessing the situation since the Russian military units were provided with food, ammunition, and fuel for only three days. In addition, Ukrainian intelligence received a lot of information from local residents, who accurately reported "how many occupiers are in each settlement and in which building they are."
