Joe Biden on Thursday will argue that President Trump’s foreign policy has emboldened authoritarian states while diminishing America’s role leading the free world, and warn that the U.S. Has “one chance to get it right” after he leaves office.

The former vice president will outline the three pillars of his vision for America’s global leadership in what his campaign is billing as a “forward-looking” address, designed to highlight both a policy area Biden has considered one of his strengths and return the focus on the battle with the Republican incumbent. 

Biden will vow to convene a summit of democratic states in the first year of his presidency and place a premium on acting in concert with U.S. allies, a senior campaign official said Wednesday in previewing the address. But the official would not say if Biden would address his 2002 vote to authorize the use of force against Iraq, another part of his Senate resume that rivals have seized on.

“There's probably a greater premium than there's ever been on working with allies and partners to deal with the greatest threats to the American people,” the official said. “No one nation acting alone can solve them and there's also no wall tall enough or strong enough to contain them. And yet, the president's 'America First' policy has actually turned into America alone.”

Biden’s three pillars would be to “repair and reinvigorate” America’s own democracy; pursue a global economy for the middle class; and putting the U.S. “back at the head of the table” in mobilizing allies to address global threats, from climate change, nuclear proliferation, cyber warfare to transnational terrorism. 

"I think from the vice president's perspective, the world does not govern itself,” the official said. "If the United States is not playing a lead role in setting rules, shaping the norms and the institutions and govern relations in nations, either someone else will do it … or, just as bad, no one does it and then you have chaos."

In South Carolina on Saturday, Biden argued there wasn’t “anyone in this race more prepared to lead the world than me.”

"That sounds like I'm bragging," he continued, "but that's what I truly believe because I've been engaged with it my entire career.” 

He acknowledged in that speech voting to “give authority to Bush” in 2002, but said that vote "didn't stop President Obama from within the first month turning me … to handle Iraq once we took office, giving me the responsibility to coordinate all the agencies, to bring home 150,000 combat troops including my son.”

The Biden campaign also previewed his attacks against Trump in a newly released digital video, which paints the president as embracing dictators, threatening war, leaving international agreements, launching trade wars and embarrassing the United States.
