Also in Slate, why President Obama should attend this year's conference.
The International AIDS Conference has returned to the United States for the first time in 22 years in recognition of President Obama’s HIV/AIDS policies.

Will his video address be greeted with shouts of “Shame! Shame! Shame!”?
Correction, July 20, 2012: This article originally misidentified Thaksin Shinawatra as the president of Thailand. He was the prime minister.
