I figured out something. Given the recent releases from Soviet archives have actually changed views of the Axis-Soviet War to include Soviet POVs more fairly in proportion to those of the Axis, there's a lot more parallels with OTL WWII than OTL Civil War. Even in the later version. First the Richmond Agreement is more of a Molotov-Ribbentrop Pact in that it defines clearly US and CS spheres of influence in regions with minorities the CSA is very bent on exterminating even at that time.
Second, the US Army is undergunned and taken by complete surprise on June 22nd, 1941 and outmaneuvered quickly, with Confederate expectations like those of the Germans for an immediate US surrender as the Germans expected the USSR to fall apart following their victories. The USA like the USSR is the more populous and richer of the two countries, the victory expected from the immediate grand tactical victories does not follow as expected. Like the USSR WRT Jews the great majority of US soldiers are nowhere near as racist toward blacks as Confederates are, but blacks don't have the easiest time of it in the USA.
The first US counterattacks led by Zhukov/Morrell backfire unpleasantly, the larger-scale counterattacks are predicted by the Confederates and flounder where they reasonably shouldn't. Richmond in this sense may resemble more Leningrad than anywhere else. To knock the USA out the Confederates try to eliminate its major industrial center, increasing dependence on their allies and increasing manpower weaknesses handicapping them. Morrell extorts out of the General Staff/US government full backing for Operation Rosebud/Uranus which encircles the CS Army in Pittsburg which surrenders in early in 1943.
The Mormons surrender, Canada rises. This is akin to the lower-level troubles the USSR had from some opportunistic subjects of the Soviet state, while Canada to some extent is like Ukraine (large, hard for the USA to control entirely, both arising from a common root). The USA clears its territory of Confederates in cleverly-executed hammerblow offensives (akin to the Soviet victories in late 1943/early 1944). It uses
Maskirovka to start victories that dramatically attenuate Confederate military power in the sense that the Soviet strikes in the Balkans and in the North gutted Axis military power through late 1943/4. The discovery of Determination is like the discovery of Majdanek and Sobibor.
Despite desperate, bitter resistance the war is already lost and the death of the dictator virtually ends the conflict, with the USA creating another satellite state in Texas to match its one up north in Quebec. Thus the counterattacks in Tennessee are akin to the German counteroffensives in late 1943, the US skill with deception tactics parallels the Soviets' increasing adeptness, the capture of Chattanooga is really Bagration (tears the heart out of Confederate military power) that of Atlanta Budapest (the end of German military reserves just like Atlanta is such for the Confederacy. Lavochkin's Looters could even be analogous to Soviet war crimes committed against the Germans by the victorious Red Army.
While the Sherman parallel is an obvious one, so could it be a parallel to the Soviet strikes in the Balkans that went a good way to winning the Great Patriotic War for them. Resemblances to the US Civil War would be such because marching to Savannah is an obvious psychological ploy.
I don't know if this makes TL-191 better or even more derivative.
