'A good day for America'
The US has had agonised debates about the wars it has been involved in and its role on the world stage. The American reaction to Bin Laden's crimes, the invasion of Afghanistan, the Iraq War, have riven the nation. But most will see the killing of Bin Laden very simply, as an act without shades of ambiguity. The good guys shot the bad guy dead. Mr Obama is trying to use it to repeat one of his main messages: how the country should come together.
"Today we are reminded that as a nation there's nothing we can't do when we put our shoulders to the wheel, when we work together, when we remember the sense of unity that defines us as Americans."
He praised the people who celebrated.
"We've seen that spirit, that patriotism in the crowds that have gathered here outside the White House, at Ground Zero in New York, and across the country, people holding candles, waving the flag, singing the national anthem, people proud to live in the United States of America."
But there is an interesting word of warning in a thoughtful article for NPR by Foreign Policy writer David Rothkopf. The author reflects: "Sept 11 was not Pearl Harbor. Al-Qaida was not and is not a historic enemy like World War II's Axis powers. Bin Laden is not Hitler."
It is a point worth making. Bin Laden could create terrible suffering and appalling disruption, but he could never actually have won. If World War II had gone a different way, Hitler or his henchmen could have ruled from Downing Street. There was never any danger of Bin Laden taking over the White House.
America has had its moment of justice. Maybe it is a moment of closure too.
