President Joe Biden said his administration has left the US safer and economically more secure, providing a strong hand for President-elect Donald Trump to play in the world. Biden highlighted achievements such as expanding NATO, rallying allies to support Ukraine against Russia, and bolstering American chip manufacturing to compete with China. However, Biden's legacy will be shaped by the fact that voters turned to Trump and his protectionist worldview. Biden also faced challenges during his presidency, including the chaotic US withdrawal from Afghanistan and conflicts in Ukraine and the Middle East.
