The USIA takes the position that even if the injury in fact requirement is met, none of the alleged injuries is likely to be redressed by a favorable judgment because importing states will necessarily reject plaintiffs' films. We reject this contention. First, we are not persuaded that all Beirut Agreement signatories employ precisely the same implementing regulations,
i.e. the regulations promulgated by the USIA. So far as we can discern, with the exception of Canada, none of the approximately sixty other Beirut Agreement participants,
see 22 C.F.R. § 502.7(e), has promulgated any formal regulations to implement the Treaty whatsoever. Nevertheless, appellants ask us to conclude that the absence of any contrary regulations establishes the
de facto adoption of the USIA's regulations by the other countries. We do not find support in fact for that conclusion.
Second, even if it could be established that all other signatory nations had adopted the USIA's regulations, appellants would still have the burden of showing that the regulations are uniformly applied. Otherwise, it could not be said that certification of plaintiffs' materials would certainly lead to their rejection by any and all importing nations. The inherent ambiguity and subjectivity of the regulations makes in our judgment such a double coincidence far less than a sure bet. Moreover, the fact that the USIA has in the past rejected films certified by Canada serves as proof that authorities in two countries with the same regulations do not always concur.
