Russian media write about this regarding the report of the NATO Defense College. They said that NATO analysts "confirmed" that Russia "uses only a small part of its resources and does not use its main trump cards" in the war against Ukraine. This is manipulation.
On July 27, the NATO Defense College published an analytical report on Russian tactics of waging war against Ukraine. However, there is not a single mention in the report that Russia is not fighting at full strength in Ukraine. Instead, it says that Russia has limited use of certain military tactics against Ukraine, but this is explained by the intention to preserve part of the forces for attacking NATO countries. The main point is that Russia did not properly prepare for the invasion of Ukraine and made a significant miscalculation regarding Ukraine and its Armed Forces. Experts write that during the invasion of Ukraine, the Russian army showed a strong material weakening of the troops and significant discipline violations. Now, Russia is deploying older weapons more often to strike the territory of Ukraine, which may indicate both the gradual depletion of the stock of high-precision weapons and the planning of a future war against NATO. The report also states that as of July-August 2022, Russia has probably reached the limit of conducting major offensive operations.
Analysts conclude that despite Russia's current apparent inability to defeat Ukrainian forces, the Kremlin still has an opportunity to correct its mistakes, strengthen its army and attack NATO countries in the future. Therefore, the Alliance needs to actively strengthen its defense, because "Russian strategic ambitions are not limited only to Ukraine."
