The next U.S. president will face a more difficult opening-day set of global problems than any of his predecessors since World War II.

The real key to Washington's pro-Israel policy is long-lasting and broad-based support for the Jewish state among the American public at large.

The secretary of state offers her defining take on Iraq, Iran, democracy promotion, and American foreign policy in general.

The West is not welcoming Asia's progress, and its short-term interests in preserving its privileged position in various global institutions are trumping its long-term interests in creating a more just and stable world order. The West has gone from being the world's problem solver to being its single biggest liability.

Despite some eerie parallels between the position of the United States today and that of the British Empire a century ago, there are key differences. Britain's decline was driven by bad economics. The United States, in contrast, has the strength and dynamism to continue shaping the world -- but only if it can overcome its political dysfunction and reorient U.S. policy for a world defined by the rise of other powers.

The United States' unipolar moment is over. International relations in the twenty-first century will be defined by nonpolarity.

What will history make of 43?

The United States needs a foreign policy that is based on reality and is loyal to American values. The next U.S. president needs to send a clear signal to the world that America has turned the corner and will once again be a leader rather than a unilateralist loner. Getting out of Iraq and restoring our reputation are necessary first steps toward a new strategy of U.S. global engagement and leadership.

The Bush administration's arrogant bunker mentality has been counterproductive at home and abroad. American foreign policy needs to change its tone and attitude, open up, and reach out. In particular, it should focus on eliminating Islamist terrorists, stabilizing Iraq, containing Iran, and toughening its stance with Pakistan.

America needs a president who can revitalize the country's purpose and standing in the world and defeat terrorist adversaries who threaten liberty at home and abroad. There is an enormous amount to do. The next U.S. president must be ready to show America and the world that this country's best days are yet to come and be ready to establish an enduring peace based on freedom.

The next U.S. president will have a moment of opportunity to reintroduce America to the world and restore our leadership. To build a world that is safe, prosperous, and just, we must get out of Iraq, rediscover the value of statesmanship, and live up to the democratic values that are the deepest source of our strength.

The current debate over the United States' failures in Iraq needs to go beyond bumper-sticker conclusions -- no more preemption, no more democracy promotion, no more nation building -- and acrimonious finger-pointing. Only by carefully considering where U.S. leaders, institutions, and policies have been at fault can valuable lessons be learned and future debacles avoided.

In the wake of the Iraq debacle, we must restore America's reputation for moral leadership and reengage with the world. We must move beyond the empty slogan 'war on terror' and create a genuine national security policy that is built on hope, not fear. Only then can America once again become a beacon to the world.

Since the Democrats regained control of Congress, the Hill has been alive with the sound of hearings. Congress' earlier slumber and recent awakening should come as no surprise: for the last six decades, the partisan composition of Congress has defined the politics of war. Now facing a Democratic majority, President George W. Bush will find it far more difficult to stay in Iraq.

The next U.S. president will face three key foreign policy challenges: setting a course for victory in the terrorists' war on global order, strengthening the international system the terrorists seek to destroy, and extending the system's benefits. With a stronger defense, a determined diplomacy, and greater U.S. economic and cultural influence, the next president can start to build a lasting, realistic peace.

Deep divisions at home about the nature of the United States' engagement with the world threaten to produce failed leadership abroad -- and possibly isolationism. To steady U.S. global leadership and restore consensus to U.S. foreign policy, U.S. commitments overseas must be scaled back to a more politically sustainable level.

Washington is as divided on foreign policy as it has been at any point in the last 50 years. As the "greatest generation" did before us, we must move beyond political camps to unite around bold actions in order to build a strong America and a safer world. We must strengthen our military and economy, achieve energy independence, reenergize civilian and interagency capabilities, and revitalize our alliances.

After Iraq, we may be tempted to turn inward. That would be a mistake. The American moment is not over, but it must be seized anew. We must bring the war to a responsible end and then renew our leadership -- military, diplomatic, moral -- to confront new threats and capitalize on new opportunities. America cannot meet this century's challenges alone; the world cannot meet them without America.

Controversies over the war in Iraq and U.S. unilateralism have overshadowed a more pragmatic and multilateral component of the Bush administration's grand strategy: its attempt to reconfigure U.S. foreign policy and international institutions in order to account for shifts in the global distribution of power and the emergence of states such as China and India. This unheralded move is well intentioned and well advised, and Washington should redouble its efforts.

Writing in Foreign Affairs, CFR's Ray Takeyh says resuming diplomatic and economic ties with Tehran could bolster Iran's pragmatists and sideline its radicals.
