The Skripal poisoning case on March 4，2018led to the expulsion of Russian diplomats from Britain and more than 20 other European and American countries.Nearly 30 years after the end of the Cold War，Russia's relations with Europe and the United States have returned to high tension.As early as 1994，Russian President Boris Yeltsin described Russia as facing the danger of“Cold Peace”.Since Crimea's entry into Russia in March 2014，Russia's relations with Europe and the United States have deteriorated sharply，with Prime Minister Dmitry Medvedev calling it a“new Cold War”and some others calling it a“mini-Cold War”.Germany is geographically close to Russia and of close economic and cultural ties with Russia，so it has been playing a special role in European and American relations with Russia.The Union Party won again in the German Federal Parliamentary elections in September 2017，and Merkel took over as German Chancellor for the fourth time in March 2018；U.S.President Donald Trump came to power in early 2017，and Russian President Vladimir Putin was re-elected in March 2018.Germany is one of the most influential countries in the EU，and Merkel's re-election guarantees German diplomatic continuity.Germany，the United States and Russia are all important countries in today's world.The birth of their respective new governments makes their relations more complicated and uncertain.However，some certainties can also be seen among the uncertainties，especially Germany's continuing commitment to easing tensions between the West and Russia in order to avoid a“new Cold War”in Europe.The“mini-Cold War”has now become a“new normal”for the security situation in Europe.The future wayoutlies in the gradually ease and improvement of the relations between Russia and the West，and in order to establish a stable structure of the European security order，the Organization for Security and Cooperation in Europe can serve as the platform.
