Seven months after his election, Emmanuel ­Macron has established himself as a force on the world stage. But at home some call him shy on the thorniest question in one of Western Europe's most diverse societies: national identity.

The young president appears in nearly every important geopolitical discussion, issuing statements and sounding alarms. Next to a Germany mired in internal divisions — and a Britain distracted by Brexit — Macron may be Europe’s most persuasive public face. And at a time of U.S. withdrawal, some argue that the 39-year-old ex-investment banker could even become the de facto leader of the free world.

In any case, he loves to play the part. This week, for instance, Macron hosts a climate summit in Paris, reaffirming global commitments to the 2015 Paris agreement that President Trump abandoned over the summer. In the presence of about 50 world leaders — and in the absence of Trump — Macron will reiterate the need for action. A particular emphasis this time around will be on private funding for climate initiatives, especially in the United States. Former New York mayor Michael R. Bloomberg, Bill Gates and other American philanthropists are also slated to attend.

The climate summit will be only the latest of Macron’s global interventions. Last week, he chastised Trump over the latter’s decision to move the U.S. Embassy in Israel to Jerusalem from Tel Aviv, and he met with Israeli Prime Minister Benjamin Netanyahu in Paris on Sunday. Last month, Macron inserted himself in the strange standoff among Saudi Arabia, Lebanon and Iran, persuading Saudi Crown Prince Mohammed bin Salman to permit Saad Hariri, the Lebanese prime minister, to fly to Paris and ultimately back to Beirut. Not to appear one-sided in the Gulf crisis, Macron last week also visited Qatar, where he secured nearly $14 billion in contracts for French companies, including the sale of 50 Airbus jets.

Within France, however, the young leader’s image does not quite match his international profile. While the French are mostly proud to have an internationally respected leader, many remain ambivalent about a character often seen as overly timid on cultural problems raging at home. Identity in general — and Islam in particular — remain crucial issues in France, yet on both questions Macron has been quiet.

“This is one where people are asking the question, ‘When is he going to speak?’ ” said François Heisbourg, a Paris-based political analyst and former presidential adviser on national security issues to Nicolas Sarkozy and François Hollande. “He will not be able to keep silent forever. It’s one of the deepest divisions in the public debate that I’ve seen in a very long time, and it’s very ugly.”

The French presidential elections this year, perhaps the most contentious in decades, saw Macron run against Marine Le Pen, the leader of the far-right, xenophobic National Front, whose fiery speeches regularly decried migrants and an “Islamist globalization” that, in her view, “threatened to bring France to its knees.” Macron defeated Le Pen in a landslide, but his victory did not put an end to the debate that her candidacy encouraged.

Lately, France has been consumed with the Tariq Ramadan scandal, which began with rape allegations against one of the most prominent Muslims in French public life. The debate almost immediately transformed from a collective discussion about sexual assault into a fight over the proper place of Islam in a staunchly secular republic. According to Le Monde, citing Elysee Palace insiders, Macron considered weighing in last week on France's secular ideals but ultimately decided against it, instead opting to speak early next year.

In the aftermath of the election, Macron largely avoided those explosive social issues, assembling an unusual centrist governing coalition and immediately setting to work on streamlining a stagnant French economy. With a party made up of novice deputies from various professional backgrounds, technocracy more than anything else has shaped the new president’s governing style.

Macron said as much at an entrepreneurial conference in Paris in June. “I want France to be a start-up nation,” he said, “a nation that thinks and moves like a start-up.”

Macron’s technocratic vision has paid off. In ways few thought possible at the start of his presidency, he stared down France’s famously strong labor unions this fall and won authorization in parliament for what probably will be the most monumental market reforms in generations. Likewise, his approval ratings, after a historic nosedive in the summer, have begun to rise, reaching 50 percent last week, according to Ifop, a leading French polling agency.

But to critics on the right and left, the “start-up nation” Macron imagines is still just a nation, replete with several long-brewing cultural and social struggles that cannot be quantified, outsourced or ignored. For many in France, the profoundly existential questions posed during the election — about what it means to be French and, most importantly, about who really belongs — remain unanswered. And while the photogenic former executive travels the globe, a number of fringe figures have started addressing the subjects Macron will not.

The formation of Macron’s cabinet saw the defection of key players from France’s traditional center-right party, Les Républicains. Their influence on the new president, especially in the economic sphere, earned Macron the reputation as “the president for the rich.” But their departure also left a party without a clear center, a void that seems to be filled by a hard-line conservative who is placing identity issues center stage.

Laurent Wauquiez — who was elected Sunday as leader of the center-right party — has promised a return "to the true values of the right," playing on France's Christian roots and what he considers the need to stand firm in the face of an Islamist threat. Wauquiez has condemned Le Pen but embraced many of her talking points.

“I want to speak to these disappointed voters who voted for the National Front,” he said this month. “We need to bring them back.”

A similar phenomenon can be seen on the political left.

Manuel Valls, a former Socialist prime minister and current parliamentary deputy, is known for his bravado on identity issues. Under Hollande’s presidency — and in the aftermath of a devastating slew of terrorist attacks — Valls led the charge against what he viewed as communitarian assaults to France’s nominally secular society.

Notably, he authorized the crackdown on the “burkini” swimsuit, a garment designed for Muslim women to wear at the beach while respecting traditional codes of modesty. For Valls, this was a means of “enslavement.”

In recent weeks, Valls has attacked what he called "the problem of Islam, the Muslims," and has reiterated that he considers it foolish to say Islamist terrorists have nothing to do with Islam. "That is to deny any responsibility to act for our fellow Muslims," he told the French newspaper Sud-Ouest this month. "We have to help them."

For some commentators, Macron’s avoidance of this debate is a testament to what they see as political intelligence, a means of avoiding a discussion that might otherwise unnecessarily divide the electorate.

"He wants to appear as a voice of reason," said Dominique Moïsi, a foreign policy expert at the Institut Montaigne, a Paris think tank linked to Macron's campaign. "There are more important problems today, with irrationality in North Korea, in Washington and Jerusalem. His thought is, essentially, 'Let's preach moderation, common sense and intelligence.' "

For others, Macron’s silence has only allowed the problem to grow. As he takes the stage Tuesday at the Paris climate summit, they wonder whether he will ever weigh in on the issues that continue to animate so many in France.

“He’s a banker; he doesn’t care about social issues. To his credit, he doesn’t think French secularism should be used against Muslims,” said Yasser Louati, a French human rights advocate. “But by remaining silent, he’s allowing the public debate to be hijacked by extremist parties. God knows why.”
