TEXT ON SCREEN: December 3, 1969

ARCHIVAL (CBS, 12-3-69):WALTER CRONKITE: In the north B52 bombers wiped out acres of dense jungle in an effort to destroy enemy artillery.

ARCHIVAL (ABC, 8-13-68): HOWARD K. SMITH: And the giant bombers giant footprints are all over the landscape.

NARRATION: During the Vietnam War, American planes pounded Vietnam, Laos and Cambodia with more bombs than were dropped by the Allies during World War II.

ARCHIVAL (ABC, 8-13-68): SPENCE: If these strikes dont kill or wound the enemy, at least they shatter their morale.

NARRATION: And land mines littered the ground.

ARCHIVAL (NBC, 2-4-69): DAVID BRINKLEY: Yesterday, the Viet Cong planted mines. Then the Americans set some mines of their own.

NARRATION: Now, four decades later, Vietnam has become a case study in how difficult it is to clean up historys battlefields once peace finally comes.

CHUCK SEARCY: Countries around the world that are now in conflict, they will face the same problem 20, 30 or 40 years from now that Vietnam is facing.


NARRATION: Princess Diana was one of the worlds most well-known celebrities. When, in 1997, she took her press entourage on an unusual trip to the war-torn country of Angola.

ARCHIVAL (ITN, 1997): PAUL HESLOP (TO PRINCESS DIANA): As you can see theyve been working away here, and theyve excavated it out and theyve uncovered a mine.

PAUL HESLOP (DIRECTOR OF PROGRAMS, UNITED NATIONS MINE ACTION SERVICE): Probably the most notable person even involved in the land mine issue was Princess Diana. I hosted her when she visited the minefields in Cuito and Huambo.

ARCHIVAL (BBC, DIARY OF A PRINCESS, 1997): PAUL HESLOP (TO PRINCESS DIANA): What were going to do now is, well place the charge here and you will detonate the mine. Youll press the button, therell be a bang, and youll have gotten rid of one of these things.

ARCHIVAL (BBC, DIARY OF A PRINCESS, 1997): PRINCESS DIANA: Two thousand people every month are killed or maimed by mines around the world. Thats one person every 20 minutes. It is my sincere hope we shall focus world attention on this vital but until now largely neglected issue.


NARRATION: It was an issue that affected more than a third of the countries across the globe. And in Princess Diana, land mine victims found a passionate advocate.

ARCHIVAL (ITN, 8-9-97):NEWS REPORT: There is a feeling of gratitude that at least someone, somewhere, royal or otherwise, does care.

NARRATION: Princess Diana advocated for a worldwide ban on land mines. A position that put her at odds with Western Powers, which still stockpiled millions of them.

ARCHIVAL (CNN, 1-15-97): NEWS ANCHOR: Dianas latest foray into international policy is drawing fire from some of her own countrymen here in Britain.

ARCHIVAL (ASSOCIATED PRESS, 1-15-97): REPORTER: Mam, the government ministers home has said you are a loose cannon by supporting this campaign. Do you have any reaction to that? PRINCESS DIANA: Im only trying to highlight a problem that is going on all around the world. Thats all.

PAUL HESLOP: She was seen as an ambassador. And it was so visual, and it was so powerful. And then she died.

ARCHIVAL (ABC, 9-1-97):NEWS REPORT: They stood for a moment of silence in Oslo today to remember Diana.BJORN GODAL: We should spare no effort at this conference to achieve the goals she had set for herself.

ARCHIVAL (ABC, 9-1-97):REPORTER: One French minister suggested that any agreement banning land mines should be called the Princess Diana treaty.

NARRATION: While the United States, Russia, China, and even Vietnam, refused to sign the 1997 treaty, saying that land mines might still be needed to protect their soldiers in times of war. The majority of the worlds countries did ratify the ban.

PAUL HESLOP: People stopped producing mines, stopped transferring mines, stopped using mines, and I think one of the consequences of signing the treaty is a lotta people thought, Well, thats fine. Thats good, and thats solved.

PAUL HESLOP: But land mines, in many senses, are the perfect soldier. They dont go to sleep. They dont need to rest. You plant them, and you arm them, and they will last for 20, 30, 40, 50 years.

NARRATION: In Vietnam, many of those perfect soldiers still lie in wait for victims.

As an intelligence officer, Chuck Searcy saw the horrors of the Vietnam War. When he went back, more than three decades later, he was shocked to see that these mines were still causing the death toll to rise.

CHUCK SEARCY (INTERNATIONAL ADVISER, PROJECT RENEW): This was our responsibility. We had created the problem. And we needed to be accountable for the damage that we had done and the damage that was continuing.

NARRATION: Land mines are only one of the dangers left behind. More than 7 million tons of ordnance, including cluster bombs, were dropped during the Vietnam War.

CHUCK SEARCY: The Pentagon estimates around 10% did not detonate as designed.

PAUL HESLOP: Cluster munitions are much more dangerous than antipersonnel mines. Theyre scattered indiscriminately over an area, and because of the mechanisms within them, theyre very unstable.

CHUCK SEARCY: Children are part of the most vulnerable population because theyre curious. They may want to pick it up and check it out and then maybe they want to throw it.

NARRATION: Ho Van Lai was 10 when a cousin picked up a cluster bomb as they played.

LAI OC: I will never forget that day for the rest of my life. People took me to the hospital. I imagined that I would become a useless person. I was supposed to be living in peace, yet I was entangled with the war.

CHUCK SEARCY: Since theres been peace in Vietnam, more than 100,000 Vietnamese have been killed or injured by bombs and mines. More than 30,000 of those are children.

NARRATION: To Searcy, the Quang Tri province next to the old dividing line between North and South Vietnam became a glaring example of what had been left undone.

CHUCK SEARCY: Quang Tri Province was the most devastated and most contaminated province in the whole country, right on the DMZ, the old dividing line between north and south. The evidence of the bombing and the continuing danger of unexploded ordnance was everywhere.

NARRATION: There, in 2001, Searcy helped start Project Renew, a de-mining organization, that also rehabilitates the injured and teaches children how to avoid the dangers underfoot.

Despite such strides, metal scavengers can still find plenty of bombs to unearth, making money from the metal casings.

CHUCK SEARCY: Theyre willing to take the risk of a loss of limb or loss of life because they might get $50 from selling this scrap metal if the bomb doesnt explode.

NARRATION: They compete with demining teams like this one. In a typical day, four decades after the end of the Vietnam War, this team can still unearth dozens of ordnances in fields, and even under homes. In May, a de-miner with Project Renew was killed while attempting to remove a cluster bomb.

The Vietnamese government estimates that it could take a century to finish cleaning up and destroying the mines and bombs left over from the Vietnam War.

CHUCK SEARCY: The job today is undone. And it will remain undone for a long time to come.

NARRATION: In September, President Barack Obama pledged to double US funding to clear unexploded ordnances left in Laos during the Vietnam War.

ARCHIVAL (9-6-16):PRESIDENT BARACK OBAMA: Given our history here, I believe that the United States has a moral obligation to help Laos heal.

NARRATION: But Vietnam and Laos are far from alone.

PAUL HESLOP: Ethiopia, Eritrea, North Sudan, South Sudan, Egypt, Libya, Western Sahara, Mauritania, Mali, the Democratic Republic of Congo, Darfur, Mozambique, Angola.

NARRATION: The list of places dealing with unexploded bombs and mines is now more than 70 countries long. And despite a 2008 cluster bomb treaty, which the US and others declined to sign, it continues to grow.

CHUCK SEARCY: Countries around the world that are now in conflict where cluster bombs and other deadly ordnance are being used, theyll face the same problem 20 or 30, 40 years from now, that Vietnam is facing.

PAUL HESLOP: This is a significant problem and its gone on for many years. Its not its not a flick of the switch, and youve solved it. The only way therell be no unexploded ordnance n rockets is for people to stop firing them at each other.
