America is back with Biden, Macron says

The United States is back as a cooperative leader of the free world under President Joe Biden, France's Emmanuel Macron has said, illustrating the relief felt by many key US allies that the tumult of Donald Trump's presidency is over.

Macron's remark on Saturday echoes that of British Prime Minister Boris Johnson who hailed Biden on Thursday as "a big breath of fresh air".

Neither Macron nor Johnson drew an explicit parallel between Biden and Trump, though both praised Biden's distinctly cooperative tone and officials said there was relief after Trump at times shocked and bewildered many European allies.

Biden, asked by a reporter if America was back, turned to Macron and gestured with his sunglasses towards the French president that he should answer that question.

"Yes definitely," Macron said. "It's great to have a U.S. president who's part of the club and very willing to cooperate."

"What you demonstrate is that leadership is partnership," Macron told Biden as they sat on an outdoor terrace with a sweeping view of the turquoise sea behind them.

Biden agreed.

"The United States, I've said before, we're back," Biden said. "Things are going, I think, well, and we're, as we say back in the States, we're on the same page."

Biden added that the United States felt very strongly about the cohesion of the NATO military alliance and expressed support for the European Union - the target of much criticism from Trump during his 2017-2021 presidency.

"I for one think that the European Union is an incredibly strong and vibrant entity, that has a lot to do with the ability of Western Europe not only to handle its economic issues but provide the backbone and support for NATO," Biden said.
