To date the best primer on the military situation in the Russia-Ukraine War using open source intelligence that I have seen is this one. The author appears to be a retired U. S. colonel presently working as a business consultant on leadership. It appears to be solid and honest.
Hit tip: SST
The war is being fought in the Ukraine, not Russia. The current ground combat area lies east of a line from Kiev to Odessa, where Russia seems to be in control, slowly destroying the Ukrainian forces. Today Russia’s air attacks were extended to the Polish border.
Russia is winning, and it will impose its demands on Ukraine: neutrality, demilitarization, denazification, independence for Donbas, acceptance of the annexation of Crimea. Israel’s President told Zelensky to accept Russia’s terms. Game over.
