My title asks a question arising from DJTrump's weekend ABC interview, the one where he promised Putin would not go into the Ukraine. All the attention has been on the question of whether he knew that Russian troops, under the guise of separatist rebels, already control the eastern part of the country. (Trump later said he knew, that blamed Obama, and when he was president there would be no change.
Earlier in discussing Estonia, I believe, Trump said that it was foolish for the US to protect nations in NATO if they didn't pay their share. (That's a loose paraphrase.) So putting the two together, I have to assume that not only is the Ukraine a member of NATO, or would be admitted on January 21, and they have borne their full share of defense costs for NATO. Otherwise Trump is inconsistent, or perhaps like other 70 year olds (and older) he's forgotten what he said before.
