 Crimea or Donbas? Ukraine's chief spy on what will be harder to reclaim? The Donbas region will be harder to reclaim as there is a continuous supply line which Russian forces can access from any direction according to Kirill Budenov, the chief of the main intelligence directorate of the Ministry of Defense of Ukraine. I believe that reclaiming Donbas will be more challenging because there is a continuous supply line and their forces can access it from any direction. Those who once held Crimea loudly and clearly said that Crimea was an impregnable fortress and everyone lost this fortress. Just as Ukraine did 10 years ago, he said, Budenov reminded that Russians still have a land corridor to Crimea today. The Crimean bridge still stands but its days are numbered. Two strategic tasks need to be solved. Cut off the land corridor and destroy the Crimean bridge. The rest is just a matter of time. The peninsula will be reclaimed. The situation with Donbas is more complicated, he said. According to Budenov, Russia will not dare to use nuclear weapons if it loses Crimea. Those who fear escalation say that if Russia understands that it will lose Crimea, it may start nuclear escalation. Do you expect me to scream in fear when I hear these words? There have been plenty of reasons for nuclear weapons use already, maybe dozens. And what do we have? In the Russian doctrine, nuclear weapons are seen as a means of deterrence. This is what everyone fears and speculates about. Budenov said, he emphasized that for Russia the use of nuclear weapons will be much more costly than not using them.
