Behind the smiles, the balloons and the red-carpet pageantry of President Vladimir Putin's visit to North Korea last week, a strong signal came through: In the spiraling confrontation with the U.S. and its allies over Ukraine, the Russian leader is willing to challenge Western interests like never before.
The pact that he signed with North Korean leader Kim Jong Un envisions mutual military assistance between Moscow and Pyongyang if either is attacked. Putin also announced for the first time that Russia could provide weapons to the isolated country, a move that could destabilize the Korean Peninsula and reverberate far beyond.
