From a New York Times column by Thomas L. Friedman headlined “Putin Is Trying to Outcrazy the West”:

With his annexation of parts of Ukraine on Friday, Vladimir Putin has set in motion forces that are turning Russia into a giant North Korea. It will be a paranoid, angry, isolated state, but unlike North Korea, the Russian version will be spread over 11 time zones — from the Arctic Sea to the Black Sea and from the edge of free Europe to the edge of Alaska — with thousands of nuclear warheads.
