Millions went to Russia.  Many more stayed in-situ, in both private life and throughout the government, and are feeding intel to Russia as evidenced by the pin-point strikes taking out missile systems, DU arms depots, etc.  Probably most of even the non-Russian speakers have been at least indirectly abused and dismayed by the behavior of the Nazis installed by the Zionist neocons in the 2014 coup and it's now pay-back time.

Almost without question the Nazis will double-down on the terrorism against the Ukranian people and almost without question it will lead to increasing levels of blow-back in a cyclic nature.  That's an Achilles' heal of managing a population using internal terrorism.  Tension builds up, then one small tear (e.g., Russia's 'special military action') rips through like wild-fire.  But again, since it's all the Nazis have and know, they are sure to double-down using characteristic methods.
