The United States has warned of "consequences" should Moscow's subversion of a sovereign country continue. It will. This is because the last time Washington warned of consequences, after the Crimea takeover, it passed a suite of sanctions against Russian officials and politically keyed-in oligarchs, but not against state energy behemoths such as Gazprom and Rosneft, or even against the main Russian banks through which the Kremlin elite ply their trade in the West. One of the oligarchs sanctioned, Vladimir Yakunin, is the head of Russian Railways (think Amtrak as a monopoly) and was also a major investor in last February's Sochi Winter Olympics.
