Bono, frontman for the Dublin-based rock band U2, has praised the United States' response to the AIDS crisis.

The 55-year-old singer-songwriter is a co-founder of the (RED) Campaign, which raises awareness and funds to help eliminate HIV/AIDS in Africa.

Bono told the AP that the best “good news story that nobody knows” about is the millions of lives the U.S. has saved.

“Do Americans know what you've pulled off? You walk down the street, nobody knows of the 15 million lives that have been saved. The majority have been saved by American taxpayers,” Bono said at a (RED)/ONE event.

“I'm amazed.”

“You're really good at beating yourselves up about what's wrong in America, what you don't do. This is what you've done that is truly, utterly great. This is the best good news story that nobody knows,” he added.
