President Barack Obama said Tuesday that US has an obligation" to help Laos recover from a brutal secret bombing campaign that destroyed parts of the Southeast Asian nation. During an address to the Lao people in the country's capital, Obama pledged $90 million in a joint three-year project with the country's government to clear ... some 80 million unexploded cluster bombs dropped during a secret US bombing campaign as part of the Vietnam War 40 years ago. "The remnants of war continue to shatter lives here in Laos," Obama said. "That's why I've dramatically increased or funding to remove these unexploded bombs." The move was welcomed by Laos President Bounnhang Vorachit as a way of strengthening mutual trust after the devastating campaign, that still maims or kills 50 people who stumble upon unexploded mines each year. Efforts to find the bombs will be aided the Pentagon, who will supply records of where they were dropped. To this day, less than 1% of the bombs have been cleared, according to US-based non-government organization Legacies of War. US funding for clearance of unexploded ordnance and victims' assistance has steadily grown since 2010. This year, Congress allotted $19.5 million, but now, for the first time, an American president has publicly recognized that the US has a responsibility to do more. "That conflict was another reminder that whatever the cause, whatever our intentions, war inflicts terrible toll, especially on innocent men, women and children," Obama said.
