(CNN) - President Obama, in his weekly address to the nation, praised the agreement of the G-20 nations to act together as a turning point in this global economic slump.
"In the end, we recognize that no corner of the globe can wall itself off from the threats of the twenty-first century, or from the needs and concerns of fellow nations. The only way forward is through shared and persistent efforts to combat fear and want wherever they exist. That is the challenge of our time. And if we move forward with courage and resolve, I am confident that we will meet this challenge."
