. . . it has to be noted that in the mid-to-late 2000s, the European Union and the Obama administration viewed Putin as a leader who was democratizing cautiously. During his first visit to Berlin, the entire Bundestag gave him a standing ovation. Then, in the Russian parliamentary elections in the fall of 2011, he had to pilfer 17 percentage points to be able to win. In the spring 2012 Presidential election, he again needed to cheat to attain a “victory,” though less so this time. I think these things have changed Putin. He realized that the policies he had pursued up until then did not automatically expand his power, so he launched a campaign of harsh repression at home (including the killing of journalists and political rivals, remaking the Russian criminal code, and restricting the freedom of assembly), and again began to assert the conquering pursuits of Great Russia.
