"Drawing on both Russian and Western sources, Tsygankov shows how Moscow's policies have shifted under different leaders' visions of Russia's national interests. He gives an overview of the ideas and pressures that motivated Russian foreign policy in five different periods: the Gorbachev era of the late 1980s, the liberal "Westernizers" era under Kozyrev in the early 1990s, the relatively hardline statist policy under Primakov, the more pragmatic statist course under Putin, and the assertive policy of the late Putin and early Medvedev era."
