It's a false analogy. Ukraine was no such source. It's just happened after WW2, that as a part or rebuilding a devastated territory, plus a better climate, resulted in USSR relocating several of its best aero/space and in general military institutions to what is now known as Ukraine. For example, their space engines engineers were educated in Russia till 2008 at least, maybe even longer.

This is literal Russian propaganda.

Yeah, sure. That's why half of my MIPT faculty in early 00's was Ukrainians from Kiev and Dnepropetrovsk that were sent there to study physics and math and rocket engines for three years, and after that they were sent back to write diploma after practice on the soviet era facilities in mentioned cities. It was the normal procedure since soviet times.
