US President Joe Biden has called on Americans to heal the wounds of his predecessor’s administration and come together as one nation.

“This is our historic moment of crisis and challenge,” Biden said during his inauguration speech on Wednesday.

“Unity is the path forward. And we must meet this moment as the United States of America. If we do that, I guarantee you we will not fail,” he said on the steps of the US Capitol, where just weeks earlier, supporters of former president Donald Trump engaged in a battle with police in an attempt to block Biden’s election from being certified.

“The answer is not to turn inward, to retreat into competing factions. We must end this uncivil war that pits red against blue, rural versus urban, conservative versus liberal. We can do this if we open our souls instead of hardening our hearts. If we show a little tolerance and humility.”

Biden also addressed the country’s allies and adversaries around the globe, pledging to undo Trump’s foreign policy moves, which he characterized as a step back from America’s global leadership role.

“America has been tested and we have come out stronger for it. We will repair our alliances and engage with the world once again .We will lead not merely by the example of our power but by the power of our example,” Biden said.

He then called for a moment of silence to remember the more than 400,000 Americans who have died from COVID-19 in the last year. “We will honor them by becoming the people and the nation we can and we should be,” he pledged.

“It’s time for boldness, for there is so much to do, and this is certain: I promise you, we will be judged, you and I, how we resolve these cascading crises of our era.”
