President Biden is now facing calls from members of the international community who want him to quit the 2024 presidential race, with even leftist Brazilian President Luiz Inacio Lula da Silva warning that “Biden has a problem.”

“He’s moving more slowly, he is taking longer to answer questions,” Lula explained to a local radio station, according to Bloomberg. “The U.S. elections are very important for all the world.” 

Biden’s first presidential debate against former President Trump last month proved to be a debacle, leading Biden to admit just days later that he “screwed up.” 

“I had a bad night,” Biden, 81, said Thursday in an interview with radio host Earl Ingram. “And the fact of the matter is that, you know, I screwed up.” 

Other European officials have reportedly started to privately argue that Biden should step aside in favor of someone with a stronger chance of beating Trump, with Vice President Kamala Harris one of the leading candidates to assume the task.

Bloomberg reported that sources familiar with high-level discussions between European officials worry about the U.S. election due to its potential impact on Ukraine and NATO at a time when Russia remains aggressive.

Biden will have a chance to reassure America’s allies during a NATO summit that he will host in the U.S. next week, with his every action under intense scrutiny. One official at the G-7 meeting in Italy last month told Bloomberg that an air of worry hung around the meetings due to Biden’s apparent cognitive issues. 

One person familiar with those conversations told The Washington Post that Italian Prime Minister Giorgia Meloni had seen Biden as “mentally on top of his game” but physically weak — concerns that grew more pronounced following the debate.

In Asia, Japan and South Korea, uneasiness has increased about a return to the strained relations of the Trump era, when his administration urged greater financial contributions for military assistance and tensions rose due to aggressive trade practices, Reuters reported.
