A true historical moment
I think the highlight of the whole ceremony was his speech, and the following abstract is my favourite part in his whole speech.
"To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect. To those leaders around the globe who seek to sow conflict, or blame their society's ills on the West - know that your people will judge you on what you can build, not what you destroy. To those who cling to power through corruption and deceit and the silencing of dissent, know that you are on the wrong side of history; but that we will extend a hand if you are willing to unclench your fist.
To the people of poor nations, we pledge to work alongside you to make your farms flourish and let clean waters flow; to nourish starved bodies and feed hungry minds. And to those nations like ours that enjoy relative plenty, we say we can no longer afford indifference to suffering outside our borders; nor can we consume the world's resources without regard to effect. For the world has changed, and we must change with it." Abstract- President Barack Obama, Inaugural speech.

That is definitely the message he is sending out and i believe what most of the world are holding onto. The differing factor between an optimist and a pessimist. It is what gives people the drive and motivation to continue inspite of all the hardships that come by. This very word allows man to look forward and strive towards a better future.
Without it, there would be nothing.
HOPE.
One word, yet holding infinite meaning.
