My deepestt conviction, the guiding principle of the administration, is that the United States of America must strive to expand the reach of freedom," Bush said. "I believe that freedom is a gift from God and the hope of every human heart."
Obama and Bush spoke along with the three other living former presidents in a rare reunion at the dedication of the George W. Bush Presidential Center. "To know President George W. Bush is to like him," Obama said.

The presidents lauded Bush's aid to the people of Africa, his effort to reach across the aisle on issues like immigration and education and his leadership in the days after the 2001 terrorist attacks. But they avoided the two wars that dominated much of his time in office – Iraq and Afghanistan.

The presidents – Obama, Bush, Bill Clinton, George H.W. Bush and Jimmy Carter – were cheered by a crowd of former White House officials and world leaders as they took the stage together to open the dedication. They were joined on stage by their wives – the nation's current and former first ladies – for the outdoor ceremony on a sun-splashed Texas morning. For Bush, 66, the ceremony also marked his unofficial return to the public eye four years after the end of his deeply polarizing presidency.

The five men have been described as members of the world's most exclusive club, but Obama said they are "more like a support group."
"Being president above all is a humbling job," Obama said. He said there were moments that they make mistakes and wish they could turn back the clock, but "we love this country and we do our best."
