I find it strange that he is asserting that things are going to plan.
Russian plan A, was a blitzkrieg, using airborne assault to capture key government buildings decapitated the government while demoralizing the Ukrainian people and the army. The pro-Russian Ukrainians would celebrate the end of the corrupt and incompetent Zelenksy government.
We are now at Plan B, or perhaps D, E, or F. Encircling Kyiv from all sides does make a lot of sense, it also make sense to take the smaller cities first in order to concentrate all the assault groups, on the grand prize, Kyiv.
The siege Kyiv is quite likely and if the bulk of the Ukrainian army is deployed there, it can be destroyed via artillery, air power, and starvation. This will be devastating to Ukrainian resistance.
The problem with Beau and many other Americans when they pronounce 'Russia has lost" is they are using the wrong timeframe. Certainly, over the next year or two, the blood and treasury that Putin puts into Ukraine is going to exceed any economic or political gains. The right time frame is a decade or even two.
The 2nd Chechen war started in 99 and by 2009 organized resistance had stopped, with the key battle being the 3 month seige of Grozny. The Syrian war is going on year 11, but the last two years have basically been a mop up operation. Now, Chechnya is only 1/30 the size of Ukraine but Syria is roughly 1/2 as large.
We are essentially only hearing the very effective Pro-Ukranian propaganda claiming that all of Urkaine is unifed against Putin. Crimea has been annexed for 8 years now, I’ve not heard of a massive resistance effort inside the air. In the breakaway regions, it appears it has been a stalemate, so clearly not all Ukrainian oppose Putin. I have no doubt that Putin, is ruthless enough to employ brutal pacification methods needed to destroy a resistance. No doubt the Ukrainian people are extraordinarily brave, but everyone has breaking point, and watching your neighbors and their families rounded up and shoot, while give pause to even bravest men. Crushing resistance is one area Russia excels at.
