In August 2017, Russian Deputy Foreign Minister Sergei Ryabkov denied claims that the US and Russia were having another cold war, despite ongoing tensions between the two countries and newer US sanctions against Russia. A University of East Anglia graduate student Oliver Steward and the Casimir Pulaski Foundation senior fellow Stanisław Koziej in 2017 attributed Zapad 2017 exercise, a military exercise by Russia, as part of the new Cold War. In March 2018, Russian President Vladimir Putin told journalist Megyn Kelly in an interview: "My point of view is that the individuals that have said that a new Cold War has started are not analysts. They do propaganda." Michael Kofman, a senior research scientist at the CNA Corporation and a fellow at the Wilson Center's Kennan Institute said that the new cold war for Russia "is about its survival as a power in the international order, and also about holding on to the remnants of the Russian empire". Lyle Goldstein, a research professor at the US Naval War College claims that the situations in Georgia and Ukraine "seemed to offer the requisite storyline for new Cold War".
