Security guarantees were in what Trump had agreed to.... not sure why people are thinking it wasnt in it as it was widely reported and understood in DC. Also Crimea is ethnic Tartars but ya know genocide kinda fucked that one up bad. Its Ethnically Russia because of what Putin has done. Dont forget the Donbass regions have fought back again and again they do not like Putin. They might be ethnic Russia but they have no love for Russia.
