The challenges America faces are great, yet we have enormous power and influence to address those challenges. The times require an ambitious national security strategy, yet one recognizing the limits to what even a nation as powerful as the United States can achieve by itself. Our national security strategy is idealistic about goals, and realistic about means.
There was a time when two oceans seemed to provide protection from problems in other lands, leaving America to lead by example alone. That time has long since passed. America cannot know peace, security, and prosperity by retreating from the world. America must lead by deed as well as by example. This is how we plan to lead, and this is the legacy we will leave to those who follow.
