Thanks to our heroic troops and civilians, fewer Afghans are under the control of the insurgency. There will be tough fighting ahead, and the Afghan Government will need to deliver better governance. But we are strengthening the capacity of the Afghan people and building an enduring partnership with them. This year, we will work with nearly 50 countries to begin a transition to an Afghan lead, and this July, we will begin to bring our troops home. In Pakistan, Al Qaida's leadership is under more pressure than at any point since 2001. Their leaders and operatives are being removed from the battlefield. Their safe havens are shrinking. And we've sent a message from the Afghan border to the Arabian Peninsula to all parts of the globe: We will not relent, we will not waver, and we will defeat you. American leadership can also be seen in the effort to secure the worst weapons of war. Because Republicans and Democrats approved the new START Treaty, far fewer nuclear weapons and launchers will be deployed. Because we rallied the world, nuclear materials are being locked down on every continent so they never fall into the hands of terrorists. Because of a diplomatic effort to insist that Iran meet its obligations, the Iranian Government now faces tougher sanctions, tighter sanctions than ever before. And on the Korean Peninsula, we stand with our ally South Korea and insist that North Korea keeps its commitment to abandon nuclear weapons. This is just a part of how we're shaping a world that favors peace and prosperity. With our European allies, we revitalized NATO and increased our cooperation on everything from counterterrorism to missile defense. We've reset our relationship with Russia, strengthened Asian alliances, built new partnerships with nations like India. This March, I will travel to Brazil, Chile, and El Salvador to forge new alliances across the Americas. Around the globe, we're standing with those who take responsibility, helping farmers grow more food, supporting doctors who care for the sick, and combating the corruption that can rot a society and rob people of opportunity. Recent events have shown us that what sets us apart must not just be our power; it must also be the purpose behind it. In south Sudan--with our assistance--the people were finally able to vote for independence after years of war. Thousands lined up before dawn. People danced in the streets. One man who lost four of his brothers at war summed up the scene around him. "This was a battlefield for most of my life," he said. "Now we want to be free." And we saw that same desire to be free in Tunisia, where the will of the people proved more powerful than the writ of a dictator. And tonight let us be clear: The United States of America stands with the people of Tunisia and supports the democratic aspirations of all people.
