Thesis (M.A.) from the year 2018 in the subject Politics - Region: Eastern Europe, grade: 110/110 cum laude, Università degli Studi Roma Tre, course: MA in International Relations, language: English, abstract: This work focuses on the concept of revisionism and on its significance for explaining Russia's current strategy towards Eastern Europe.

How defensive-revision-prone are these contexts? This work focuses on the concept of revisionism and on its significance for explaining Russia's current strategy towards Eastern Europe.

More specifically, a precise kind, centred on inner mechanisms and on defensive dimension of this co
