Was Zeman right about sanctions?

The White House's National Security Strategy states that "American leadership is a global force for good" but is grounded in the U.S.'s "enduring national interests." In other words, what is in the U.S. national interest constitutes the global good. "There is no substitute for American leadership," the document says. The U.S. will help its allies "deter Russian aggression" and "resist Russian coercion over the long term, if necessary," the document adds, but "will keep the door open to greater collaboration ... should [Russia] choose a different path." Rightly or wrongly, the U.S. media are interpreting John Kerry's meeting in Sochi last week as a sign of recognition that the attempt to isolate Russia is failing and that other interests - Iran, Syria - are now at the top of the U.S. agenda. Has Miloš Zeman been proven right? Sanctions aren't working? What are the Havelians to do now? Start protesting against the U.S. for cozying up to Russia?
