Barack Obama took office at a moment of crisis unlike any America had seen in decades – a nation at war, a planet in peril, the American Dream itself threatened by the worst economic calamity since the Great Depression. And yet, despite all manner of political obstruction, Obama’s leadership helped rescue the economy, revitalize the American auto industry, reform the health care system to cover another twenty million Americans, and put the country on a firm course to a clean energy future – all while overseeing the longest-stretch of job creation in American history. On the world stage, Obama’s belief in America’s indispensable leadership and strong, principled diplomacy helped wind down the wars in Iraq and Afghanistan, decimate al Qaeda and eliminate the world’s most wanted terrorists, shut down Iran’s nuclear weapons program ,open up a new chapter with the people of Cuba, and unite humanity in coordinated action to combat a changing climate.
