Since his inauguration in 2009, President Obama has upheld FDR's vision of America as a nation that keeps its word - a nation still committed to uphold the 'four freedoms' that President Roosevelt set down in the great Atlantic Charter of August 1941.

Our only president who has died as U.S. commander in chief in war is Franklin Delano Roosevelt - who died of a cerebral hemorrhage or massive stroke on April 12, 1945, only three weeks before the unconditional surrender of the German armed forces he had laid down as implacable Allied policy two years before.

No one ever said learning was to be easy, but it's part of the process of evolving as a human being, and we all have to go through it. When I look back, I see that each difficult time brought an important lesson. And I prefer to look at it with gratitude because I wouldn't be who I am today if I haven't gone through it all.
