The lines between the World Cup and diplomacy have always been blurry. On Tuesday, US Secretary of State John Kerry wrote an opinion piecein the Washington Post about the need to reach a comprehensive nuclear deal with Iran, as the 20 July deadline to reach a final agreement rapidly draws near. Perhaps with sport on his mind, he wrote: "There may be pressure to put more time on the clock."

By escaping from the Group of Death at the World Cup, the United States finally gave the lie to the notion that Americans were bad at soccer. Except Americans were never bad at soccer. The good soccer players just didn't know they were Americans. 

Watching World Cup matches while drinking tax-free imported beer is an important part of diplomacy at the United Nations. The roars and groans of the thousands of diplomats who represent the UN’s 193 member states and support their national teams are loud enough to be heard across the world body’s New York headquarters. Right now, at least, international competition is taking center stage over cooperation on unrest in Iraq, the Syrian civil war and conflicts in Africa.

No matter how entrenched animosities in the Middle East may be, one principle is upheld by all: never miss an opportunity to miss an opportunity. The controversy over access to broadcasts of World Cup matches makes that clear. Pricing by Qatari entities holding World Cup rights for the Middle East and North Africa, including Al Jazeera's belN Sports channel, puts broadcasts beyond the reach of many football fans in the region. Inevitably, that is a public issue in a soccer-crazy part of the world. 

Soccer used to be their game -- the Europeans, the South Americans, the Africans. Today it is our game too, bringing the nation together in a passionate embrace of its athleticism, its skill and, yes, its excitement. But it hasn't always been this way. Even after the U.S. hosted the World Cup for the first time in 1994 -- setting attendance records that still stand today -- many still dismissed soccer as somehow not quite American.

When al Shabaab, the violent Islamist group in Somalia, took control of the capital city Mogadishu, it actively destroyed buildings and overt displays of Western institutions and influences. This included outlawing soccer. The group destroyed cinemas and viewing centers in Mogadishu during the 2010 World Cup to stop residents from watching the matches. Their first successful international attack was the twin explosions in Uganda’s capital Kampala at viewing stations during the tournament. 

Faced with a smothering and frustrating Italian defense in a must-win World Cup game Tuesday, the Uruguayan superstar responded with his front teeth. The incident, visible on television replays and circulating on the Internet, showed Suarez apparently bite the shoulder of Italy defender Giorgio Chiellini as the pair clashed in the Italian penalty area. The apparent chomp happened in an instant, but became a worldwide sensation and could lead to Suarez being kicked out of the World Cup.
