It's a time-honored tradition: When a U.S. president gives his State of the Union address, interest groups pore over the carefully crafted remarks line by line, word by word, to assess the administration's priorities and blind spots. The exercise plays out, if to a lesser degree, overseas as well: The day after President Obama's sixth address, news outlets in Kiev, Beijing, and Tehran are picking apart references to their countries.

All happy speeches are alike. All unhappy speeches are different in their own particular way. We connoisseurs of the diplomatic public speaking art are fortunate to have one example of a high-profile public speaking occasion where everything that could possibly go wrong did indeed go wrong. If you are working at an Embassy or in a Foreign Minister’s office and are looking for a model for how not do it, seek no further.

It wasn't a reassuring moment. Speaking at the World Economic Forum in Davos, Switzerland on Wednesday, Shinzo Abe, the Japanese prime minister, compared recent tensions between China and Japan to the rivalry between the British and German empires at the start of the 20th century.

A new Asian diplomatic row broke out on Monday after China unveiled a memorial to a Korean national hero who assassinated a Japanese official a century ago - with Tokyo condemning him as a “terrorist”. In 1909, Ahn Jung-geun shot and killed Hirobumi Ito, Japan’s first prime minister and its top official in Japanese-occupied Korea, at the railway station in the northeast Chinese city of Harbin.

Thirty years ago, after the fall of Argentina’s military dictatorship following defeat in the Malvinas/Falklands war with Britain, a newly elected President Raúl Alfonsín created the Human Rights Commission known as Conadep (Comisión Nacional sobre la Desaparición de Personas, or National Commission on the Disappearance of Persons). The first of its kind, Conadep’s main purpose was to investigate the crimes committed by the preceding military dictatorship and bring its perpetrators to justice.

In Italy's Alps, at the border with Austria, there's a land where people speak in German and dream of independence. Once part of the Austro-Hungarian empire, it was annexed by Italy at the end of World War I. But even today, not a single drop of Italian blood runs through the veins of its more than 500,000 inhabitants.

Ever since Ariel Sharon sank into a coma eight years ago, many have wondered whether he would have taken the peace process with the Palestinians any further after the 2005 withdrawal from Gaza. A series of cables from the U.S. Embassy in Tel Aviv to the State Department that were leaked to Wikileaks show that in fact, even before the Gaza withdrawal, Sharon was planning his next big diplomatic move.

Winston Churchill would fit in perfectly with today’s social media culture. His style was to communicate constantly, interpreting events as they unfolded, and explaining what he intended to do in real time. Churchill’s astute observations and keen wit helped to build his towering reputation as a great leader. Although public speaking was the primary medium of the day, Churchill was a prolific writer who came up with some of the best, less-than 140 character quotes in history.
