WASHINGTON (AP) — The U.S. and Russia could find some common ground for cooperation as authorities investigate the two ethnic Chechens accused of carrying out the Boston Marathon bombings.

Ties between the two former Cold War adversaries have been soured by disputes from stopping Syria's civil war to child adoptions. But understanding how the brothers became radicalized is of paramount importance to Washington. And it's also important to Moscow, which has long battled terrorism in its southern territories.

But the tragedy also risks hardening resentment. Under President Barack Obama and Prime Minister Vladimir Putin, efforts to "reset" relations have faltered. Even counterterrorism coordination has sometimes been strained.

Much depends on how the two countries mobilize the emotions a week after one of the most significant terrorist attacks on U.S. soil since 9/11.
