Perhaps the best argument I've seen for ceding Crimea to Russia in order to avoid a possible nuclear attack. The problem with promoting nuclear blackmail is addressed at
49:40. Acton claims that China has already been deterred from invading Taiwan ten times over. He says promoting nuclear blackmail by rewarding Russia is greatly overblown. This seems terribly short-sighted to me.
Acton claims the trigger for possible Russian use of nuclear weapons would be a large scale land invasion of Crimea. Curiously, he seems to totally ignore the most likely way Ukraine will assault Crimea which is with a siege, just like they did with the city of Kherson by cutting off most heavy transport across the Dnieper. He goes so far as to claim that the ability to cut off Kherson was a unique geographic situation that does not pertain to Crimea!!!
Acton also ignores what Biden says he will do if Putin uses nukes: massive (presumably non-nuclear) retaliation that would quickly end the war. Acton seems to see only two possibilities: ceding Crimea to Russia soonish, or ceding Crimea to Russia after Russia uses nukes which would have much worse ramifications. So he suggests the West cut off support from Ukraine before it invades Crimea.
ISTM if this is a possibility the West wants to keep open then the slow ramp up military aid makes sense in order to let Ukraine take back land to the pre Feb. 2022 borders but not enough for them to attack Crimea. Of course, this will lead to a situation where the land bridge to Crimea is cut, the water supply to Crimea is cut, and (presumably) the Kerch bridge to Crimea is cut. It's doubtful that ceding Crimea to Russia at this point would lead to a stable political situation. If Russia keeps Crimea then it's going to want/need a water supply and a land bridge. This is one of the reasons they attacked Ukraine in 2022.
The unstated dilemma is that Putin needs a "win" to save face and stay in power. But by giving him a "win" we are rewarding and promoting wars of imperialistic expansion. Another unstated problem is that Ukraine's stance on ceding Crimea changed fundamentally after the atrocities at Bucha and elsewhere were discovered.
It seems obvious to me that the plan Acton proposes is one of the best ways possible to ensure nuclear weapons get used. Cutting off aid to Ukraine before they take Crimea is telling Putin he can have Crimea and we won't stop him because we are afraid of his nukes. Ukraine may not win but they're not going to stop at the border of Crimea. We then face the situation Acton says is most likely to cause a nuclear strike but with the West putting vastly less restraint on Russia, basically giving him a green light.
