On April 3 and 4, 2009, the heads of state and government of the 26 members of the North Atlantic Treaty Organization (NATO) will meet in Strasbourg, France, and Kehl, Germany for a summit marking the 60th anniversary of the alliance. The summit will be one of three stops on President Obama's first official visit to Europe as President. Alliance leaders are expected to use the anniversary summit to pay tribute to NATO's past achievements and to reaffirm their commitment to the alliance as the preeminent transatlantic security framework.
