A change has come to the world. Barack Obama's inauguration as the 44th president of the United States has ushered in a new age.
Exactly what this means is difficult to define and where we are headed is uncertain. What is clear is that a seismic shift in history is under way and riding on it are our highest hopes.
Driving our expectations are a series of global crises, foremost among them the financial meltdown, climate change and terrorism. Mr Obama is taking office promising to deal with each, capping his pledges with the catch cry, 'Yes we can'.
He has no top-level leadership experience and we have nothing but his rhetoric and high-profile cabinet choices to assure us. Regardless, there is no more qualified person for the job.
Politics put him in office and no matter who he is there will be those who love or loathe him because of that. But there is no getting away from his being a breath of fresh air to a position that has had more lows than highs of late.
None of his predecessors in the past few decades has taken office amid so much hoopla. A recent New York Times/CBS News poll showed that 79 per cent were optimistic about the Obama presidency; never before have so many people turned out on the streets of Washington to celebrate the swearing into office of a new commander-in-chief.
