There's also the fact that keeping the stars home for the FIBA tournament is a cop out when it comes to the US's vested involvement in international basketball doesn't get brought up often enough.
Is it a cop-out if the US continues to win?
That's a good question -- and it's a hard one to answer since there's no good way to measure it against the relative importance of the FIBA tournaments for the average NBA player. If you're a member of a FIBA international team, you want to play against the best the US has to offer, because if you beat them, you didn't beat their best players, and if you lose, you still didn't get to play against the best competition in the world.
If you're someone that's good enough to play in the NBA, like, uh, Rudy Fernandez or Luol Deng, something, it would kind of suck playing against USA rookies and sophomores year in and year out. Not to mention the message it sends from the NBA to the rest of the world.
