Sun Tzu taught that actions always speaking louder than words. In Sun Tzu's strategy, the value of informaiton is often more easily understood in terms of costs. Verbal statements cost little or nothing to make and are always open to a wide variety of interpretations. Physical actions, however, no matter how minor, always involve some cost. This is why the most tivial actions, such as crossing a little stream such as the Rubicon, can have such an large impact.
For example, the most important information from the upcoming conference in Annapolis is simply who attends and who does not. Attendance alone splits the world into two camps: those who want to seek a peaceful resolution of the problem of Palestine and those who do not. It draws a new line in the Muslim world separating Hamas and Iran from the rest of the people in the region, including, suprisingly, Syria. While I have little doubt that some of the attending nations, such as Syria, will use the opportunity repeat the familiar anti-Zionist formulas, those words must be interpreted in a new way. In a very real sense, the people in the region are recognizing that Iran, not Israel, is the real threat to their peace and security. Iran has given Syria millions, perhaps billions of dollars. Israel recently bombed a suspect Syrian nuclear site. And yet, Syria sees more of a future in meeting with Israel and the rest of the Middle East than staying with Iran.
