Sunday’s final concluded a monthlong tournament that presented a jarring contrast between Brazil’s hosting of the tournament and its achievement on the field. The World Cup was well organized despite fears that it would be chaotic. The Brazilian people were hospitable. The soccer was largely attractive and attacking. Some have called this the best World Cup in recent memory. Soccer became so absorbing that widespread protests - against perceived wasteful spending on the World Cup and the 2016 Rio Olympics - did not occur after undermining a warm-up tournament last year.

Germany and the United States sought on Sunday to restore vital ties badly frayed by a spying row which led to the expulsion of the CIA station chief in Berlin. Secretary of State John Kerry emerged from talks with his German counterpart Frank-Walter Steinmeier to offer reassurances that the two vital transatlantic allies remain "great friends". In a bid to lighten the atmosphere and use sports diplomacy, Kerry even wished his counterpart "good luck" in Sunday's football World Cup final when Germany will take on Argentina.

The team that lost this week is trying to beat the other team that lost this week. It's Brazil versus Netherlands -- honestly, I may have that wrong -- and at this point, even Brazilian supermodel Adriana Lima is barely interested. From a geopolitical balance-of-power perspective, does anyone care who comes in third? Is there a war in history where a country took home (at least, what was left of home) the proverbial bronze medal? After President Bush declared Mission Accomplished in the Iraq war, did he announce a run-off between Afghanistan and Iran? 

While U.S. and Iranian negotiators labor to reach a long-term nuclear agreement, other Americans and Iranians are stepping up contacts in a new wave of people-to-people diplomacy. In recent months, three American religious delegations have visited Iran while the first group of female Iranian seminary students came to the United States. Sports exchanges are also on the rise again,spearheaded by American wrestlers who find far more numerous and passionate fans in Iran than in many countries, including the U.S.  

For a country that staked its political future on projecting soft power by using the World Cup as a means of promoting national unity, that decision now appears to have been misplaced. Brazil must now assume the risk of letting its citizens decide how best to create a nation that provides opportunities for all with greater public security and less inequality for those who really want to create a zone of peace in South America. 

As the Brazil team has come spectacularly undone in the World Cup, the pain for the host country has been compounded by the prospect that its hated rival, Argentina, could still lift the championship trophy on Sunday in Rio de Janeiro’s fabled Estádio do Maracanã, after Argentina won a tense semifinal against the Netherlands in a penalty shootout on Wednesday afternoon. The tens of thousands of Argentine fans who have invaded Brazil to cheer for their team, and taunt their hosts, brought with them a song that predicts not just triumph for Argentina, but deep humiliation for Brazil.
