New Diplomatic Strategy To Be Put To the Test in Russia

President Barack Obama’s diplomacy is about to get a stern test in Russia, home of a wary public, a two-headed leadership and a lingering bit of hard feelings.

The president arrives in Moscow on Monday for a full-scale two-day summit, the first of its kind since the early part of the George W. Bush presidency. He is sure to emerge with tangible signs of progress — including another step toward the world’s two largest nuclear powers reducing their arsenals — thanks to agreements negotiated before he shows up.
