The president of the United States, Joe Biden, began a six-day tour of Peru and Brazil this Thursday, where he will attend the APEC and G20 summits, in a context in which the return of Donald Trump to the White House leads to leaders around the world to discuss how to address future changes in American foreign policy. The Air Force One plane took off from Andrews Air Base, outside Washington, shortly after 11:15 a.m. local time (16:15 GMT), and is expected to land around 5:45 p.m. (22:45 GMT) in Lima, where Biden will remain until on Sunday, the day he will travel to the Amazon and then head to Rio de Janeiro to attend the G20 summit. These summits will be the last that Biden will attend before handing over power to Trump on January 20, ending a half-century political career, much of it focused on foreign policy, and offering him one last opportunity to strengthen the Washington alliances before leaving the Presidency. Biden has become what is known in US political jargon as a “lame duck”, a president in his last term in office with influence diminished by the proximity of his successor’s inauguration.
