[Photo/Agencies] President Xi Jinping's call to "build a community with a shared future for mankind" will have an even better chance of being realized, should the United States be ready to move beyond challenges and seize new opportunities. With its recent general election, the Capitol Hill riot on Jan 6 in Washington, DC, and the impeachment trial of former president Donald Trump behind it, the US must now transition from challenges, moving on to opportunities and new solutions. The nation should recall the words of then president Abraham Lincoln in his annual message to Congress on Dec 1, 1862, during the Civil War: "It is not 'can any of us imagine better?' but, 'can we all do better?'... We must disenthrall ourselves, and then we shall save our country.... Fellow citizens, we cannot escape history.... We shall nobly save, or meanly lose, the last best hope of Earth."
