Russian sociologist Igor Eidman presents a tribute to his cousin, the physicist and statesman Boris Nemtsov. Eidman implicates President Vladimir Putin in Nemtsov’s death, arguing that antagonism between the two politicians and Nemtsov’s criticism of Putin led to his assassination. In Eidman’s opinion, this murder demonstrates Russia’s further decline into authoritarianism. He concludes by calling upon the international community to hold the Russian government accountable for Nemtsov’s death and take action against Putin’s regime.
