RIO DE JANEIRO -- The announcement came in October 2009: International Olympic Committee President Jacques Rogge opened the envelope at a ceremony in Copenhagen and told the world that Rio de Janeiro had won the 2016 Olympic Games.

Crowds watching a live broadcast on Rio’s famous Copacabana Beach exploded into a delirious uproar. Ticker tape swirled, a giant banner reading “Rio Loves You” was unfurled, and a samba club took to the stage.

In Copenhagen, then-President Luiz Inácio Lula da Silva declared: “This is the moment for Brazil.” TV Globo called it “a dream in an envelope.”

Seven years later, and less than a week before the games begin, many Brazilians are hoping that dream does not turn into a nightmare.

Brazil in 2016 is a more troubled country than the confident new global player Lula hoped to crown with Olympic glory. And Dilma Rousseff, the successor he chose, is suspended for an impeachment trial while the interim government formed by her former vice president, Michel Temer, struggles with a Zika epidemic and a recession.

In Rio, things are even worse. The state government is broke, and violent crime has risen. Promises to treat 80 percent of the sewage flushed into Guanabara Bay before Olympic sailing races take place there have been abandoned.

Two people died in April when part of a new elevated cycle path collapsed into the sea after a wave hit it. And Olympic delegations arriving at the Athletes’ Village complained about the state of the apartments — some even refused to stay there.

And local news outlets are reporting that neither Lula — the president who helped them win the Games — nor Dilma will attend the opening ceremony.

Here's a look back at the many things that have gone wrong for Brazil in the past year.
