SAO PAULO — Jair Bolsonaro was sworn in as Brazil's president Tuesday, taking the reins of Latin America's largest and most populous nation with promises to overhaul myriad aspects of daily life and put an end to business-as-usual governing.
For the far-right former army captain, the New Year's Day inauguration was the culmination of a journey from a marginalized and even ridiculed congressmen to a leader who many Brazilians hope can combat endemic corruption as well as violence that routinely gives the nation the dubious distinction of being world leader in total homicides.
A fan of U.S. President Donald Trump, the 63-year-old longtime congressman rose to power on an anti-corruption and pro-gun agenda that has energized conservatives and hard-right supporters after four consecutive presidential election wins by the left-leaning Workers' Party.
Bolsonaro is the latest far-right leader to come to power by riding waves of anger at the establishment and promises to ditch the status quo.
Tuesday's festivities in the capital of Brasilia began with a motorcade procession along the main road leading to Congress and other government buildings. Bolsonaro and his wife, Michelle, stood up in an open-top Rolls-Royce and waved to thousands of onlookers.
They were surrounded by dozens of guards on horses and plain-clothes bodyguards who ran beside the car.
Brasilia was under tight security, with 3,000 police patrolling the event. Military tanks, fighter jets and even anti-aircraft missiles also were deployed. Journalists were made to arrive at locations seven hours before festivities began, and many complained on Twitter of officials confiscating food they had brought for the wait.
The increased security came at Bolsonaro's request. His intestine was pierced when a knife-wielding man stabbed him at a campaign rally in September, and he has to wear a colostomy bag. His sons, politicians themselves, insist their father could be targeted by radicals, but security officials have not spoken of threats.
Bolsonaro did little moderating since being elected in October, with progressives and liberals decrying stances that they say are anti-homosexual, sexist and racist.
The incoming president, who spent nearly three decades in Congress, has also drawn international criticism for his plans to roll back regulations in the Amazon and his disinterest in social programs in a country that is one of the world's most unequal in terms of income.
On the economic front, where Bolsonaro will ultimately lead Latin America's largest economy is unknown, as during the campaign he reversed course from previous statist stances with pledges to lead market-friendly reforms. He also promised to overhaul Brazil's pension system and privatize several state-owned companies, which has given him wide support among financial players.
Bolsonaro says he will prioritize the fight against crime in a nation that has long led the world in annual homicides. More than 63,000 people were killed last year. Human rights groups fear his defense of police violence could shield officers from investigations of misconduct and lead to more extrajudicial killings.
The most notable foreign leaders planning to attend the inauguration are also associated with far-right movements: Israeli Prime Minister Benjamin Netanyahu and Hungarian Prime Minister Viktor Orban.
Leftist Presidents Nicolas Maduro of Venezuela and Daniel Ortega of Nicaragua, deemed dictators by Bolsonaro, were uninvited by Bolsonaro's team after the foreign ministry sent them invitations. The United States was represented by Secretary of State Mike Pompeo, though Trump tweeted his congratulations.
"The U.S.A. is with you!" Trump said Tuesday on Twitter after praising Bolsonaro's inaugural address.
Seven of Bolsonaro's 22 Cabinet ministers are former military personnel, more than in any administration during Brazil's 1964-1985 dictatorship. That has sparked fears among his adversaries of a return to autocratic rule, but Bolsonaro insists he will respect the country's constitution. Bolsonaro's vice president is a retired general, Hamilton Mourao.
Bolsonaro's Liberal and Social Party will have 52 seats in Brazil's 513-member lower house, the second largest bloc behind the Workers' Party.
Michael Shifter, president of the think tank Inter-American Dialogue, believes the president will have trouble achieving major changes.
"The obstacles are formidable, including in the business community. In some cases, necessary reform will clash with the business interests and incomes of large numbers of lawmakers," Shifter said.
