Hours after the Boston bombers were identified as Chechens, President Vladimir Putin of Russia called President Barack Obama to offer help with his investigation.
Putin long has argued that Russia faces the same threat of radical Islam in the northern Caucasus as the West does elsewhere. The Boston bombings seem to support him.
He is right in one respect. The war in Russia's southern underbelly no longer is a separatist conflict. The nationalist cause that inspired Chechen fighters 20 years ago is now an Islamic one. However, this mutation has as much do with Russia's ruthless actions in the region as with the global spread of Islamist fundamentalism.
So far America, Russia and even the insurgents agree that Dzhokhar and Tamerlan Tsarnaev, the Boston bombers, acted on their own. The self-proclaimed Caucasus Emirate, a jihadist organization, says that it played no part.
Nonetheless, America's investigators find it hard to understand how a regional conflict in Russia might resonate tragically in Boston.
Struggling to integrate in America — “I don't have a single American friend,” Tamerlan, the older brother, once said — the Tsarnaev boys sought mental refuge in their native land. The Internet and social networks that served as a channel created an illusion of engagement without experience or memory. The brothers never fought in the Chechen wars or lived in Chechnya for any length of time, yet their lives and their sensibilities seem to have collided with its violent and tragic history.
After the mass deportation of Chechens by Stalin in 1944, the Tsarnaev family landed in Kyrgyzstan, where the boys later grew up. Their grievances were stirred by separatists who declared Chechnya's independence after the end of the Soviet Union in 1991. When Russia launched a “small, victorious war” against Chechnya in 1994, nationalism was the main cause. By the end of the first war, 50,000 were dead, Chechnya was in ruins — and nationalism had been superseded by Islam.
