A number of dangerous, disquieting and scary things happened today in the unfolding Ukraine Crisis. Russia is a revisionist, nuclear power. In today’s lengthy and bellicose speech, Vladimir Putin barely mentioned NATO. He focused on his long-attested belief that Ukraine is not a real country and is only separated from Moscow by historical accident and perfidy. Beyond wanting to bring Ukraine to heel he made broad and menacing statements that brought the whole post-Cold War settlement into question.
