It can sound cliché to say the spirit of the Olympics is about more than winning gold. With Simone Biles’ exit, the U.S. gymnastics team may have redefined success at the Olympics and set a new standard for supporting a teammate.

In the hunt for solutions to hunger, there’s a global shift from focusing on increasing farm production to reducing food waste – and not just at fancy restaurants.

As students move from remote to in-person learning, our reporter found that some U.S. districts are experimenting with enhanced summer school programs as a bridge to help sharpen social skills and catch up on academics.

Our London columnist looks at the best way to stop a new arms race in cyberwarfare. Could Beijing, Moscow, and Washington lead the way?

If a legal system recognizes the dignity and rights of all citizens, that sends a message of equality and fairness to the rest of society. Canada, this month, gained its first nonwhite Supreme Court justice. In Colombia, the Constitutional Court is translating key decisions into 26 Indigenous languages.

Steps in the right direction, even if small, need to be noted – especially when the stakes involved are high.

This week, North and South Korea announced they would resume communication with each other after more than a year of silence. “The whole Korean nation desires to see the North-South relations recovered from setback and stagnation as early as possible,” the official North Korean news agency said.

United Nations Secretary-General António Guterres and an unnamed senior U.S. official quickly nodded their approval.

Some 13 months ago, in a display of displeasure, the North blew up a joint liaison office (unoccupied at the time) that had been constructed in its territory for the purpose of better communication with the South. It was seen as a dramatic signal of a new era of chilly relations with its southern neighbor.

That move followed a showy 2019 summit between North Korean leader Kim Jong Un and then-U.S. President Donald Trump. The United States sought to persuade North Korea to give up its nuclear missile program in exchange for an end to economic sanctions on it. But no agreement emerged.

Mr. Kim’s aim still seems to be to use the threat of building a stockpile of nuclear missiles capable of reaching the U.S. mainland as a way to win concessions, but without giving up the nuclear arsenal.

In itself the fresh move to reopen communication with South Korea, a longtime U.S. ally, doesn’t get at the nuclear standoff. But it’s a welcome start.

Changing times may be forcing Mr. Kim into new approaches. The threat from the COVID-19 pandemic and the effect of economic sanctions may be taking a toll.

North Korea does not admit to having any cases of COVID-19, and no signs of starvation or social unrest have been observed as a result of the sanctions.

But after making a splash with a large delegation at the 2018 Winter Olympics in South Korea, Mr. Kim has kept his athletes home from the Tokyo Games now underway. His concerns over the possibility of spreading the pandemic in his country, which maintains tight controls on its borders, may have outweighed the opportunity for any propaganda victories from attending these Games.

In January Mr. Kim displayed some uncharacteristic contrition, acknowledging the economic challenges his country faces and saying that he had learned “painful lessons.” He may have decided that warming relations with South Korean President Moon Jae-in now represents the best path to influencing the U.S.

“Our patience will achieve more than our force,” Edmund Burke, the 18th-century statesman and member of the British Parliament, once observed. More favorable conditions for peace on the Korean Peninsula, and a lessening of nuclear tensions, may be emerging. Those who long to see t​hose results must remain open to each opportunity that offers progress.
