Ukraine Could Strike Devastating Blow to Putin as Military Struggles
https://www.newsweek.com/ukraine-could-strike-devastating-blow-putin-crimea-1773386This article makes the case, that holding Crimea will be a challenge for Russia.
Are all parts of Ukraine that Russia holds logistically vulnerable? No. There are three regions of Russia that Ukraine occupies.
Region 1:
The strip of land along the border of Russia, About 250 miles long, 50 to 100 miles wide. No portion of this region is more than 100 miles from Russia.
It also has a lot of Russian separatists who lived their.
This is a near ideal region for an invader to hold. No long exposed supply lines leading to the home country. No major waterways to cross with long vulnerable bridges or ferry routes.
If Russia cannot hold this region, or at least a strip that is 50 miles wide, or 20 miles wide, they would really be in a sorry state indeed.
Region 2:
The strip of land along coast of the Sea of Azov, 250 miles long, 60 to 70 miles wide.
Highly vulnerable. Supply columns have not have up to 50 or 100 miles to travel across Ukrainian territory, but up to 250 miles. If this is cut in a couple of places, requiring an advance of just 70 miles, it provides a dangerous trap. With the world's most shallow sea to their back, no evacuation is practicable. The Russia fleet could not help.
Region 3:
Crimea.
If Region 2 is taken, the Crimea Land Bridge, Crimea becomes very vulnerable. All that is needed is a precision missile strike from the north shore of the Azov Sea to take out that bridge. Crimea would be far more cut of than Kherson was three months ago. Not a relatively narrow river with many crossing point, but a wide sea several miles long to cross.
The far more competent Russian army of 1942 was unable to hold Crimea against a German offensive that was, at the time, starting to near it's limits of logistical support. Nor were the Germans able able to hold Crimea once the Russians isolated it in 1944. The Crimea is a classic trap for any defensive army trying to hold it.
Logistics is critical in war. It dictates that Russia should be able to hold Region 1, or at least part of it. But unless they start showing a lot more competence next year, with their new amateur conscript and convict army, than the professional army did last year, I don't think they can hold Regions 2 or 3. We shall see.
This is why President Zelenskyy has made Crimea an objective that Ukraine insists on having before there can be peace. He has good reason to believe that they can take it.
Your average Russian, at least a year ago, didn't know much about Kherson, or Bukhmut, let along Soledar. But they do know about Crimea, the Siege of Sevastopol, the great Russian naval base there, the triumph of Yalta. Putin's hold of power will not survive the lose of Crimea. But until it falls, he's safe. His potential successors want the fall of Crimea to happen under Putin's watch, not theirs.
