Sgt. Henry Johnson and Sgt. William Shemin are being awarded the Medal of Honor by President Obama at a White House ceremony for their heroics in World War I.

This seems to be Henry Kissinger's ultimate dream - a dream that one can glimpse in his latest book, Germanically entitled World Order: Reflections on the Character of Nations and the Course of History.
