President Trump met with his French counterpart Emmanuel Macron on Saturday - a visit that began with a spat as dozens of leaders came together to commemorate the centennial anniversary of World War I's end and all that has since been built between nations in a multilateral world.
He first lady Melania Trump skipped an arrival ceremony at the residence of the French president earlier in the day and did not walk down the Champs-Elysees with other world leaders, traveling to the Arc de Triomphe in the US president's bullet-proof limousine, instead.
Numerous leaders, including German Chancellor Angela Merkel, met at the Élysée Palace before travelling to the Arc de Triomphe together in motor coaches.
One hundred years later, Macron will pay tribute to those soldiers and their families in an address delivered at the foot of the Arc de Triomphe, built by Emperor Napoleon in 1806, where an unknown soldier killed in the Great War is buried.
The world leaders were scheduled to gather at precisely 11 a.m. Paris time, the moment of the cease-fire - but apparently arrived a bit late, the Associated Press reported. Pins of artificial poppies are worn in the lead up to Armistice Day.
The White House did not say why the president chose not to motorcade when taking a helicopter was no longer an option.
At least one other topless protester also made it into the avenue, but was unable to reach the cars.
Police tackled the woman and the motorcade continued uninterrupted.
"FEMEN activists "welcomed" the cortege of @realDonaldTrump twice on his way to Arc de Triumph", she wrote.
France on Saturday attempted to defuse a row sparked by President Emmanuel Macron's comments about a European army which angered US President Donald Trump, suggesting his remarks had been misinterpreted.

In January, a federal judge in California barred the federal government from ending DACA. Since then, Republicans and Democrats have been unable to compromise.
It's been fueled by Trump himself, who has proudly identified himself as a nationalist as he advances an "America First" agenda.
After a meeting at the Elysée Palace, Mr Macron said he agreed that Europe should pay more.
First, Macron failed to persuade Trump not to withdraw from the 2015 Iranian nuclear deal.
"The aim of the forum is to show that there are lots of forces in the global system - states, NGOs, foundations, intellectuals, companies - who believe we need a world of rules, an open world and a multilateral world", he said. "We have a lot of problems".
The Forum is part of the "fightback" against nationalism worldwide, chief organizer Justin Vaisse told AFP as he played down the significance of Trump's decision not to attend.
They are likely to meet at the G-20 summit in Buenos Aires later in the month. The two could wind up chatting at a lunch Macron was hosting for world leaders following Sunday's ceremony.

The geographical spread of the leaders in attendance showed how the "war to end all wars" left few corners of the earth untouched but which, little more than two decades later, was followed so quickly and catastrophically by the even deadlier World War II. The White House cited a scheduling conflict, saying the president instead would attend a Veterans Day ceremony to pay respects to USA soldiers who died on French soil.
