Rio 2016: Athletes' passion always overcomes Olympic problems, sports historian says

With less than two weeks until theopening of the 2016 Olympic Games in Rio de Janeiro, Brazil, many are wondering whether organizers can actually pull off the event in the midst of a direeconomic situation and worries ranging from security to the risk of Zika virus infection.

But this is far from the first time people have doubted whether a host country can pull off a successful Olympic Games, says David Wallechinsky, president of the International Society of Olympic Historians.

"This happenseven in the most successful games," saidWallechinsky, who is also a broadcast commentator andhas been to16 Olympic Games."And then the minute the competitions begin, it all shifts to the athletes."

Even in extreme situations whereterrible things have actually happened, such as a deadly pipe bomb explosion in Atlanta in 1996 and the murder of 11 Israeli athletes and nine hostages in Munich in 1972, "the competitions continue."

"You've got 10,000 athletes who have been waiting for this and so that's a powerful force," he said."That energy of those 10,000 athletes kind of pushes through, you know, the Olympics no matter what bad things happen."

Still,Wallechinskyacknowledges the situation facing Rio is historically unique.

"What you have different here is a country in chaos," he said, noting that Brazil has seen "a real change of fortune" since it was chosen in 2009 as the host city.

In addition to economic collapse and a looming vote on whether to impeach Brazilian president Dilma Rousseff, the country continues to battle the mosquito-borne Zika virus.

The onlyOlympic event that has been significantlyaffected by a public health issue, Wallechinsky said, was the Nanjing2014 Youth Olympic Games, during the Ebolaoutbreak.Three athletes were prevented from attending after a decision not to allow people from Ebola-affectedcountries to compete in "water or combat sports," he said.

Some of the issues Rio faces "are very serious," Wallechinsky said.

"The water quality for the sailing events is really disturbing," he said. People there talked to him about it when he visited two years ago, he said,calling it "a scandal" that the event would be held in polluted water when there were "pristine waters, you know,50 kilometres away."

There are also significantconcerns about infrastructure, Wallechinsky said.

Here are five Olympics that were plagued by concerns and problems, either in the lead-up or during the events themselves but the Games went on.

London 2012

There were "dire warnings" before the London Olympics in 2012,Wallechinskysaid.

Amid concerns about the event being apotential target for attack,Britain hired a global security firm, G4S, to bring in 10,000 staff.

But just weeks before the Games were to begin, G4S acknowledged it wouldn't be able to meet that target.

The British government called in 3,500 extra troops to fill in the gap and thehead of G4S made a public apologyand pledged to pay the costs of the military deployment.

Athens 2004

Like Rio, Athens was facing financial hardship going into the 2004 Olympics,Wallechinskysaid, but the organizerswere "able to grab some money ... from the governnment."

Still,"they didn't complete everything in time," he said, and the quality of infrastructure was a problem. He remembers rushing up the stairs at the women's water polovenue when he felt something "funny" beneath his feet.

"It was the stairway chipping away as I ran up the stairs,"Wallechinskysaid, noting that sometimes, Olympic venues are built hurriedlyand are not designed to last.

But nothing collapsed, and the Games hosted 301 events that year one more than the previous Olympics in Sydney and reached anaudience of3.9 billion people through television coverage, according to the International Olympic Committeewebsite.

Atlanta 1996

"The1996 Atlanta Olympics were a mess," Wallechinskysaid.

The transportation system was overcrowded and disorganized,thecomputer results system didn't work during the Games, and security wasn't adequate, he said.

A bomb exploded in Centennial Olympic Park on July 27,the ninth day of the Games,leaving two people dead and more than 100 injured.

Atlanta "was almost the template for how not to do things," Wallechinsky said.

From a sports perspective, theAtlanta Olympics did have some shining moments,especially for Canada, as it earned more medals than ever before in a non-boycotted Olympics.Sprinter Donovan Bailey won two gold medals,rowers Marnie McBean and Kathleen Heddle won the double scullsand Clara Hughes brought home two bronze medals for cycling.

Barcelona 1992

Wallechinsky recalls a couple of issues leading up to the Barcelona Olympics in 1992. There were concerns that thepreparations wouldn't be finished on time. But in the end,"they pulled it off," hesaid.

There was also a problem with polluted waters where the sailing competitions were taking place.Wallechinsky remembers plastic bags floating in the area. But, he said, it wasn't as bad as thesituation Rio is facing.

Munich 1972

The 1972 Munich Olympicsstand out as one of the most tragic Games in history,with themassacre of 11Israeli athletes and coaches by a Palestinian militant group called Black September.A West German police officer was also killed and five Palestinians died.

The Games paused after the crisis, but then resumed in defiance of the attackers.
