On July 14, 2015, Iran agreed to a nuclear deal with the U.S and other world powers that would keep the country from acquiring a nuclear weapon. Since that time, the International Atomic Energy Agency says Iran has complied with initial requirements to reduce its stockpile of uranium. In return the U.S. and the international community have eased many economic sanctions that have stifled Iran for years. But critics say there’s no guarantee that Iran will maintain the agreement long term and they question what happens 15 years from now when the deal expires. 

In the port town of Tanmen, on China's southernmost province of Hainan Island, I met 35-year-old Wang Zhenzhong. He's done pretty well for himself. He graduated from college in Beijing and he runs his own business, selling handicrafts related to the town's maritime culture. He likes to play the guitar.

Like many folks here, his ancestors were fishermen. But one thing that makes Wang different from his neighbors is that he and his family are in possession of something very ancient and very rare.

An international tribunal in The Hague has invalidated China's claims in the South China Sea in a first-ever ruling. The decision has been rejected by Beijing.

The disputed waters are claimed by China, Taiwan, Malaysia, the Philippines, Vietnam and other countries. But China has been the most aggressive in staking out its claim — marking a "nine-dash line" around the bulk of the islands and waters, and building up artificial islands within the disputed region.

How's this for British irony: The United Kingdom is about to get a new prime minister, Theresa May, who voted in favor of keeping the country in the European Union.

By voting to leave the EU in a June 23 referendum, U.K. voters turned the country's politics upside down and prompted the immediate resignation of Prime Minister David Cameron, a strong backer of remaining in the European body.

Now Cameron's dominant Conservative Party has found a successor, May, the home secretary and a longtime member of Parliament — who also favors staying in the EU.

What gives?

Human trafficking is a global problem. But it's not something that just happens overseas. Minors are exploited throughout the United States, even in Connecticut. In recent years, the state and federal governments have passed legislation to increase penalties for people who use children as commodities whether for sex or labor. State agencies like the Department of Children and Families have partnered with anti-trafficking organizations to help victims become survivors.

Voters in the U.K. have decided to leave the European Union, a decision that has shocked Europe, shaken global markets and pushed Prime Minister David Cameron to announce his upcoming resignation.

The EU referendum vote was decisive — 52 percent to 48 percent in favor of dissolving the United Kingdom's 43-year membership in the European community. But Northern Ireland and Scotland voted in favor of remaining, raising the specter that the United Kingdom itself may break apart.

It's easy to think of borders as fixed, almost sacrosanct lines, so rooted in the natural order of things that it often doesn't occur to us to question them. But borders were not always thought of this way. In fact, the notion of well understood, and agreed upon boundaries between nations is somewhat new.

Hillary Clinton didn't just take aim at Donald Trump's national security policies in a major speech Thursday. She declared him unfit to negotiate with allies, command U.S. forces or be privy to the nuclear code.

"Americans aren't just electing a president in November — we're choosing our next commander in chief, a person we count on to decide questions of war and peace, life and death," Clinton said in San Diego. "It's not hard to imagine Donald Trump leading us into a war just because someone got under his very thin skin."

President Obama announced Monday that the U.S. is fully lifting a five-decades-long arms embargo against Vietnam.

The embargo on lethal military equipment had been partially lifted in 2014; now it will be raised fully, the White House says. The president spoke about the decision from Hanoi, during the first day of a weeklong trip to Asia.

West Hartford officials are planning to buy a University of Connecticut property instead of allowing a for-profit international school to come to town.

There's a debate in West Hartford over plans by a for-profit company to open an educational academy for Chinese students in town. The plan would include sending some students to the public high schools.

What are the pros and cons in allowing international students into our public schools at a time when districts face declining enrollment and budget constraints? Is this a creative way to fund public schools or is it detrimental to their mission?

Ten years ago, Democratic political newcomer Ned Lamont launched a bid to unseat his party’s incumbent U.S. senator. He defeated Joe Lieberman in the primary and brought national political attention to Connecticut. But 2006 was also the year that our show launched. This hour, we look back at that campaign with Lamont and talk about what has happened in the state and country since then. 

Championing "stability" and protectionism, Donald Trump managed a sendup of the foreign policies of the last three American presidents, as well as the candidate he is likely to face this fall in a general election — Hillary Clinton.

"With President Obama and Secretary Clinton, we've had ... a reckless, rudderless and aimless foreign policy — one that has blazed a path of destruction in its wake," Trump charged in a sober foreign policy address at a hotel in Washington. He added, "[T]he legacy of the Obama-Clinton interventions will be weakness, confusion and disarray."

China has gotten very good at making steel. And making it and making it and making it.

In fact, that "excess" production is causing such a crisis for the global steel industry that the United States is joining an international push to try to cut the glut.

At least 28 people have been killed and more than 320 wounded in an attack in Kabul. The assault targeted a key government security agency and included a suicide car bombing and an offensive by armed militants. The Taliban has claimed responsibility.

The attack hit at about 9 a.m. local time, during morning rush hour — one reason there are so many casualties, NPR's Philip Reeves reports. It comes about a week after the Taliban announced the start of their spring offensive.

President Obama’s visit to Cuba last month was historic for that country, and for relations between Cuba and the U.S. For many Cuban Americans living in the U.S., this trip, and the warming relationship between the countries, doesn’t wipe away those barriers of pain and separation.

Ivan Backer narrowly escaped the Holocaust, and for the last 70-plus years, he's been trying to give back.

In a landmark vote on Sunday evening, Brazil's lower house of Congress, the Chamber of Deputies, supported impeaching President Dilma Rousseff, The Associated Press reports. The vote was 367 to 137 with seven abstentions. Two deputies were not present. The total easily surpassed the two-thirds majority required to send the proceeding to Brazil's Senate.

Secretary of State John Kerry visited the Peace Memorial in Hiroshima on Monday, making him the highest-ranking U.S. official to visit the site since the U.S. dropped an atomic bomb there at the end of World War II.

Kerry didn't apologize for the U.S. attacks on Hiroshima and Nagasaki in 1945, as some Japanese activists have pushed for. He did honor those who died in the bombings, NPR's Elise Hu reports.

On the visit, Kerry toured the peace museum and laid a wreath at the monument to the attack, The Associated Press reports.

One law firm, 11.5 million files.

The massive trove of emails, contracts and other papers from Panamanian law firm Mossack Fonseca is being called the largest document leak in history.

More than 50 world leaders are attending a nuclear security summit in Washington this week. But Vladimir Putin is a no-show. And, as if on cue, North Korea fired a ballistic missile on Friday.

These biannual nuclear summits, aimed at locking down fissile material worldwide that could be used for doomsday weapons, were proposed by President Obama back in 2009, barely two months into his presidency.

"We must insure that terrorists never acquire a nuclear weapon," he declared, calling such a scenario "the most immediate and extreme threat to global security."

Ever stood on the coastline, gazing out over the horizon, and wondered what's on the other side? Pondered where you'd end up if you could fly straight ahead until you hit land?

Turns out the answer might be surprising. And even if you pulled out an atlas — or, more realistically, your smartphone — you might have trouble figuring it out. Lines of latitude won't help, and drawing a path on most maps will lead you astray.

Every election, there's that chorus of people who insist they are moving to Canada if candidate so-and-so wins. Everyone knows these people. They're tweeting and Googling about it as you read this. One Nova Scotia island is even specifically appealing to the anti-Trump crowd.

U.S. Secretary of State John Kerry says that Americans were among those killed in Tuesday's terrorist attacks in Belgium's capital, which killed at least 31 people and injured hundreds more.

Speaking in Brussels on Friday, Kerry said he was grieving with "the loved ones of those who have been very cruelly taken from us — including Americans."

The director of the State Department Press Office has since specified that two U.S. citizens were killed in the attacks.

It's the first confirmation of American deaths in the attacks.

Authorities have identified a third suspected suicide bomber in the terrorist attacks on Brussels this week.

A Belgian federal prosecutor's statement says the person seen on the left in a widely circulated surveillance footage still, previously identified as a suspected attacker, is 24-year-old Najim Laachraoui.

In Syria, Russian-backed government troops have entered the ancient city of Palmyra after days of intense clashes with Islamic State militants.

The Syrian Observatory for Human Rights, which monitors the conflict, says regime troops have pushed into the southwest corner of the city. Observatory Director Rami Abdel Rahman says advances inside the city are slow, as ISIS planted mines in areas where it retreated.

State news agency SANA reports that the army took control of Mount Altar, a strategic point west of the city's famed ruins.

The Islamic State has been steadily losing territory in its self-declared caliphate in Syria and Iraq, where a U.S. bombing campaign and a host of rival forces chip away at its holdings.

Yet the Brussels bombings again demonstrated the group's potency much farther afield, from terror attacks in Western Europe and North Africa to seizing control of Libya's coastal city of Sirte.
