Except for Ukraine losing control of its foreign policy, requiring Ukraine to allow adoption of Russian as an offical language in certain areas to the detriment of ethnic Ukrainians living there, treating promotion of Ukrainian culture, customs, and identity as a sordid crime to be punished and eradicated, the terms were just dandy, in a boot-on-neck sort of way. Boris Johnson must be the diplomat of the millenium to have convinced Ukrainian nationalists to spurn a dreamy deal like that...
Just for fun, the entire nation including Zelinsky was Russian speaking. Ukrainian was a boutique language, sort of like Gaelic, welsh, or Navajo. People learned it to show how cultural they were. But it wasn’t some new concept that Russian would be spoken in Ukraine along with any other language.
But ethnic cleansing was very important to the Reich. They wanted to erase the language, and kill as many people in the Donbass as they could for the crime of not going along with the Kiev coup.
And they could never agree with anything vilifying nazism. Gotta have that Bandera Avenue, got to use Nazi symbols on your military uniforms, gotta name your battalion after Oscar Dirlewanger.
