In these four years, Americans have seen the unfolding of large events. We have known times of sorrow, and hours of uncertainty, and days of victory. In all this history, even when we have disagreed, we have seen threads of purpose that unite us. The attack on freedom in our world has reaffirmed our confidence in freedom's power to change the world. We are all part of a great venture: To extend the promise of freedom in our country, to renew the values that sustain our liberty, and to spread the peace that freedom brings.
