'Breathtaking speed': Trump's Paris trip marks return to global stage as leaders turn 'the page' on Biden

First Lady Jill Biden will also attend the ceremonies, but it's Trump who will be holding court with world leaders.

The president-elect's appearance will serve as Trump's unofficial return to the global stage, and it is another reminder that he is quickly becoming the center of the world's attention.

"This is without question a major moment in French history and the fact that Macron wanted to share it with Trump speaks to the significance of what Trump is achieving even before he gets to the Oval Office again, said Brett Bruen, a public affairs and strategic communications veteran, and former U.S. diplomat who served under both Democratic and Republican administrations.

"He is being feted quite literally in Paris with all the glitz and glamour," Bruen, president of the Global Situation Room, added.

And Bruen and other analysts give credit to Macron for inviting Trump to this weekend's festivities.

Trump has taken a slew of calls in the weeks since the November election from international leaders congratulating him on his White House victory. 

Trump argued that Canada had failed to prevent large amounts of drugs and undocumented people from crossing the northern border into the U.S. and also pointed to America's massive trade deficit with Canada.

Trump has also weighed in recently on a number of international conflicts. In the volatile Middle East, the president-elect warned this week in a social media post that there would be "ALL HELL TO PAY" if Hamas does not release all the hostages held in Gaza before he is inaugurated on Jan. 20.

But Biden, likely on his last overseas trip before Trump takes over in the White House next month, is already being overshadowed on the world stage by his predecessor and successor.

"While President-elect [Trump] is still weeks away from taking the oath of office, loyalties and the attention of world leaders has shifted to the incoming President and from Washington to Mar-a-lago with breathtaking speed," Wayne Lesperance, a veteran political scientist and president of New England College, told Fox News.

Matt Mowers, a veteran GOP national public affairs strategist and former diplomat at the State Department during Trump's first administration, made the case that "Biden's essentially been a lame duck" for months and that "world leaders have been shifting their gaze to the next administration.

While members of the Biden White House would likely disagree with such sentiments - especially after the current administration played a large role in hammering out the cease-fire that halted fighting in Lebanon between Israel and Hezbollah - it is undeniable that world leaders have already started to engage directly with the incoming president and administration.

While the spotlight traditionally shifts from the outgoing to the incoming president, Mowers argued that "it is more pronounced this time because the difference in the Biden and Trump approach to foreign policy is so different."

Mowers emphasized that Trump is already aiming "to shape world events" by "being bold, not timid, in the statements he's putting out, and the world is already reacting to that kind of American strength."

Matthew Bartlett, a Republican strategist who served at the State Department during Trump's first term, told Fox News that "the world is demanding leadership" and that "the Oval Office has been replaced by Mar-a-Lago."

Lesperance, pointing to Biden's swing through Africa, noted that lame duck presidents' final weeks are "usually filled with celebratory moments and efforts to cement one's legacy. Often the focus is on their role on the world stage on behalf of America and its allies.'

However, he argued that "Biden's pronouncements on Ukraine, Gaza and the importance of climate change go largely ignored by world leaders. Instead, they focus on Trump's picks for his foreign policy team and pronouncements about changes in U.S. foreign policy position. It's pretty evident that while Biden attempts a victory tour, the world has turned the page."
