Credibility

I’ve never been quite sure what the phrase “international community” is supposed to mean. Isn’t that, like, everyone? Still less do I understand how this community can have a greater or lesser degree of credibility, but Condi Rice says (while standing next to her “good friend,” Equatorial Guinea’s dictator, as every blogger and his uncle have pointed out) that the UN must slap down Iran hard (take “strong steps”) in order “to make certain that we maintain the credibility of the international community on this issue.” Credibility with whom? The Martian community?
