The Kremlin is also faced with the threat that Ukraine with Western aid will destroy the dam across the Dnieper River, flood Kherson and sweep away Russian artillery positions and pontoon bridges, leaving highly trained special force troops isolated and subject to capture.  The capture of Russian special forces would be a major propaganda victory for Ukraine.  https://southfront.org/kiev-to-launch-dam-war/ 

The Kremlin could not have made a more stupid mistake than going to war with insufficient troops in a half-hearted manner that gave Washington every opportunity to expand the war, subject the Kremlin to an extended period of damaging propaganda, and portray the Russian military as ineffective.  The image of the Russian military and its leadership that the Kremlin's blunder has created is the last thing Russia needed.  Russia needed a show of force that would quickly end the conflict before the West could react, a show of force that would intimidate Europe from further participation in Washington's aggression against Russia.  Instead, hesitancy, indecision, undefended red lines, and half-way measures opened the gates to the road to Armageddon. As the provocations of Russia intensify from  the attack on the Crimea bridge to the destruction of the Nord Stream pipelines to the deployment of the 101st US Airborne Division in Romania, to the practice of a nuclear attack on Russia on Russia's border,  and now to the threat of a false flag dirty bomb loaded with radioactive material and the destruction of the Russian city of Kherson by flooding, before long Putin will be faced with a crossed red line that he cannot ignore.
