Worldwide Support for Development (WSD), a nonprofit philanthropic organization that holds a variety of summit meetings on global welfare, held the fourth Global Opinion Leaders Summit, at which former U.S. President Barack Obama spoke about denuclearization and world peace, in Tokyo on March 25.
The summit's speakers were Obama, WSD Chairman Haruhisa Handa, former New Zealand Prime Minister John Key and WSD Honorary Advisor Brendan Scannell, who is also the former Irish ambassador to Japan. The event was livestreamed by the Associated Press and Reuters.
The audience was comprised of around 2,200 attendees, many of whom had seen the WSD's advertisements and applied for seats.
