Its hard to see how Kherson can stay under Russian control. They are cut off from supplies and reinforcements and casualty replacements. At the moment they seem to only be able to get a ferry across once in while, before it is again sunk. And all the ferry approaches are under fire also. They dont have a usable airfield there, as these are under fire.
Its worse than Dien Bien Phu. They dont have the French fleet of C-47’s that could at least parachute supplies.
That is unsustainable. And that is why there has been buzz for several days about Russians negotiating either surrender or withrawal.
One problem for Ukraine, to be realistic, is that with no electricity they will be severely hampered, including the trains, which commenters on You Tube say are electric, and used to move troops and heavy equipment.
Thoughts?
OTOH, it seems to me Russia if it succeeds will inherit a depopulated devastated Eastern Ukraine. What the “F” (pardon my French) can they do with it, besides it being a huge liability? They sure as heck don’t have the extra people to repopulate it, as in past episodes. This is as opposed to a Ukraine victory, in which case huge Western energy and resource investment will come in.
