The German newspaper Frankfurter Allgemeine Zeitung set up a list of politicians, who "won" and "lost" in 2015.
Among the winners, the newspaper named Russian President Vladimir Putin.
"Russia proved to be a constructive partner in the negotiations on Iran's nuclear program; moreover, the Russian involvement in the Syrian conflict led to the fact that its resolution became impossible without Putin," the newspaper wrote.
At the beginning of 2015, Russia had strained relations with the West, but by the end of the year the situation had changed, the article said.
According to the newspaper, the year was successful for US President Barack Obama as well.
