I'm opposed to having NBA teams in Europe. Europe already has successful professional leagues. Wanting to get a piece of that pie makes no sense to me.
On the other hand, I would love for the NBA to get involved in a true professional league World Championship. That would be the best way to bring the world basketball community together. The NBA champs would surely win the title for the first few years, but I think it would motivate Europe to eventually catch up.
Basketball; the international game.
