Short answers, pulled from the story.
USA Basketball was founded in 1974 as the Amateur Basketball Association of the United States of America (ABAUSA). It was renamed USA Basketball on the 12th of October 1989, after FIBA modified its rules to allow NBA players to compete in international competitions.
The chairman of the board of USA Basketball is retired General Martin Dempsey. The organization's CEO is Jim Tooley.
USA Basketball represents the United States in FIBA and in the United States Olympic and Paralympic Committee for both the men's and women's national basketball teams.
The renaming followed a rule change by FIBA that allowed NBA players to compete in international competitions. Professionals from Europe and South America had always been permitted to compete, so the change removed the amateur restriction that had previously applied to American players.
USA Basketball selects and trains national teams for the FIBA Basketball World Cup, the FIBA Women's Basketball World Cup, the Olympic Games, the Pan American Games, the World University Games, and various age-group championships from the U16 level upward, as well as 3x3 competitions.
The pandemic led to the cancellation of the 2020 U17 World Championship, the 2020 U18 Americas Championship, and the 2022 Youth Olympics. The 2020 Olympic Games were postponed to 2021, and the 2021 Summer World University Games were postponed to 2023.
