Nuclear Issues

Lt. Gen. Clapper (ret.) James Clapper discusses his experiences in Korea, and how to change the narrative on the peninsula. 

In a "policy memo" to President-elect Donald Trump, Graham Allison and Dimitri K. Simes write: "The two Chinese characters that make up the word “crisis” can be interpreted as meaning both “danger” and “opportunity.” Russia today offers your administration not only a serious challenge but a significant opportunity.

Russia is no longer the Evil Empire the United States confronted over decades of Cold War. Nonetheless, Russia remains a player whose choices affect vital U.S. interests profoundly across the agenda of global issues. First and foremost, Russia remains the only nation that can erase the United States from the map in thirty minutes.

Our government's inattention has allowed North Korea to establish a new and dangerous threat to the Asia-Pacific region. It is probably too late to reverse that damage, but serious attention to this problem can still limit the extent of the damage.

The fallacy in the Bush administration's appointment of a commission to study intelligence failures is that there is almost never such a thing as a pure intelligence failure. Intelligence failure is usually linked to policy failure.

The new secretary of DHS would do well to address our vulnerabilities before the terrorrists do.

THE NUCLEAR bomb dropped on Hiroshima became an icon of the nuclear age, seared into the collective consciousness of postwar Americans by John Hersey's classic book. Fewer Americans remember much about the destruction of Nagasaki three days later on Aug. 9, 1945, and fewer still have reflected on lessons it offers for threats we face today.

In the past week, Russia celebrated the 14th anniversary of its declaration of state sovereignty, and a state funeral in Washington marked the death of Ronald Reagan, the United States' 40th president. Both events remind us how much has changed since the collapse of the Soviet Union and the end of the Cold War.

What is the gravest threat to the lives and liberties of Europeans and Americans today? Europeans and Americans differ profoundly in their answers to this fundamental question. Recent conversations with 100 security experts at NATO in Brussels and in Berlin, London and Athens underscored for me just how profoundly.
