Russia underestimated Ukraine’s resistance, which has led to unbearable losses
. British intelligence said that the underestimation of the Ukrainian resistance and the losses suffered did not allow Vladimir Putin to announce the military success of his army on May 9. According to British intelligence, Russia’s invasion plan was most likely based on the mistaken assumption that the Russian military would meet limited resistance and be able to surround the Ukrainian settlements quickly. It is noted that this assumption forced the Russian troops to try to conduct the initial stage of the operation with a straightforward approach designed to achieve a quick victory with minimal losses. “This miscalculation has led to unbearable losses and a further reduction in Russia’s operational focus,” the statement said.
