Liebensborn was a NAZI program to increase births for the Fatherland. It started out as SS officers impregnating German women at a almost factory level process but was spread to conquered territories where SS soldiers impregnated acceptable women. They also took children from the families of acceptable conquered nations (mostly the Nordic countries, but also Netherlands, Poland and others) to raise as "German". Generally all Jewish children were killed as being untermenschen, 'subhuman'. BTW the NAZIs didn't start truly million level mass liquidation of the Jews and others until 1942 with the Wannsee Conference where Rheinhard Heydrich lead the planning for "the Final Solution". That's when mass murders accelerated into killing millions instead of just 10's and 100's of thousands. But the seeds for this horrendous mass murder were planted wih the complete dehumanization of the Jews, the Roma, the disabled and others that didn't fit into the master race plan. Russians have massacred civillians during this war with impunity. What makes you think they won't expand that if they take more territory?There is a rather large difference between castration by the hundreds and murder by the millions.
Or even relocation by force. I never heard of the NAZIs abducting Jewish children in order to raise them as German.
If we call all murder by the hundreds or thousands "Genocide" then the world will become desensitized for when we ring the alarm bells when actual genocide is happening. The attempt to kill an entire nationality/ethnicity.
If Ukraine wins this war they have their land back and they will survive not just as a country but as a people. If Russia wins Ukraine will no longer exist and the Ukrainian people as well. Russia has actually done this before in the 1930's with Stalin deliberately starving millions to death, the Holodomor.
