REPLAY - UN General Assembly: Joe Biden's first UN speech as US president

President Joe Biden defended the chaotic U.S. withdrawal from Afghanistan on Tuesday in a speech to the United Nations, arguing it was a necessary step to pivot US policy to focus on a global challenge from anti-democratic systems, the Covid-19 pandemic and climate change. Biden said the world is facing a decisive decade and that addressing a variety of challenges "will hinge on our ability to recognise our common humanity." He said that "instead of continuing to fight the wars of the past, we are fixing our eyes" on challenges such as the global pandemic, addressing climate change, cyber threats and managing the shift of "global power dynamics."
