President Obama was already making big plans for an eight year White House stint in 2008 and according to the New Yorker's Ryan Lizza. His biggest priorities? climate change and reducing nuclear proliferation.
Obama has an ambitious second-term agenda, which, at least in broad ways, his campaign is beginning to highlight. The President has said that the most important policy he could address in his second term is climate change, one of the few issues that he thinks could fundamentally improve the world decades from now. He also is concerned with containing nuclear proliferation. In April, 2009, in one of the most notable speeches of his Presidency, he said, in Prague, “I state clearly and with conviction America’s commitment to seek the peace and security of a world without nuclear weapons.” He conceded that the goal might not be achieved in his lifetime but promised to take “concrete steps,” including a new treaty with Russia to reduce nuclear weapons and ratification of the 1996 Comprehensive Nuclear Test-Ban Treaty.
