The Berlin Wall wasn't the only barrier to fall after the collapse of the Soviet Union and the end of the Cold War. Traditional barriers to the flow of money, trade, people and ideas also fell.
China is ruthlessly pragmatic. It supports North Korea for its own selfish interests. And I believe that China no longer considers us an ally. The current president, Xi Jinping, cultivates close relations with South Korea. He has never met with me, the leader of North Korea, something that the leader of China has always done. At the grand celebrations in Beijing two years ago commemorating the 70th anniversary of the end of World War II, he placed the president of Russia and the president of South Korea at his side. In North Korea, we pay a lot of attention to ceremonies and what they signal.
We all accuse Vladimir Putin of Cold War nostalgia, but Washington's elites - politicians and intellectuals - miss the old days as well. They wish for the world in which the United States was utterly dominant over its friends, its foes were to be shunned entirely, and the challenges were stark, moral, and vital. Today's world is messy and complicated. China is one of our biggest trading partners and our looming geopolitical rival. Russia is a surly spoiler, but it has a globalized middle class and has created ties in Europe.
