The president opens the trip on a more intimate note. After landing overnight, he has a lunchtime meeting with Pope Francis, the head of the world’s 1.3 billion Catholics.

They have met three times already, but this is their first tete-a-tete since Biden was elected.

Only the second ever Catholic president, Biden attends mass regularly and is open about his faith and how it has helped him through a series of family bereavements.

The White House said it expects the meeting to be “warm”, and certainly Biden and the pope share a range of concerns, from poverty to climate change and the coronavirus pandemic.

But the question is whether either leader raises the red-button issue of abortion. Biden supports the right to choose, while Francis, 84, has slammed terminating pregnancies as “murder”.

The pontiff has nonetheless distanced himself from a push by conservative US bishops to deny communion to politicians supportive of abortion rights—which would include Biden.

The meeting will be behind closed doors and the Vatican abruptly cancelled a live camera feed, to protests from journalists. It was also cancelled for an earlier meeting between Francis and South Korean president Moon Jae-in.

Charm offensive

Biden then crosses the Tiber into the heart of the Eternal City to meet prime minister Mario Draghi—the man, dubbed “Super Mario”, tasked with reforming Italy after the devastation of Covid-19.

The G20 host, a former head of the European Central Bank famous for his efforts to save the euro from collapse, is being closely watched in Washington for his plans to set debt-laden and politically fractious Italy back on track.

But while Draghi is feted as the new star of European politics, particularly with the exit of German Chancellor Angela Merkel, Biden appears to have lost some of his shine.

The president is banking his domestic legacy on passing the $1.75 trillion Build Back Better social welfare package, and also hopes it will present the US as a global leader on climate change at the crucial COP26 summit starting on Monday.

He said it includes “the most significant investment to deal with the climate crisis ever” -- 550 billion dollars to cut greenhouse gas emissions.

“America is back in a leadership position on climate in a way that will be broadly welcomed,” National Security Advisor Jake Sullivan told reporters on the flight over.

Biden, a veteran foreign policy expert, is determined to distance himself from the unilateralism of ex-president Donald Trump, and will be seeking to soothe ruffled feathers.

He will have some fence-mending to do after a chaotic withdrawal from Afghanistan, which irritated US allies, and a major spat over nuclear-powered submarines.

Biden will meet Friday with French president Macron for the first time since the subs row, in what Sullivan said was expected to be a “constructive and deeply substantial meeting”.

Paris was furious after Australia ditched a big deal to buy French submarines last month, saying it was negotiating a new defence pact with the US and Britain.

Biden and Macron are expected to meet again Saturday alongside Merkel and Britain’s Boris Johnson to discuss attempts to get Iran back into negotiations on submitting its nuclear industry to international inspections.

A perhaps more turbulent meeting, with Turkish president Recep Tayyip Erdogan is planned for Glasgow next week.
