Yes, exactly. Thank you. So when you said "the copyright holder orally waived his right to sue for copyright infringement," that was completely off-base, wasn't it? In truth, because copyright law does not speak to taking North America-only software out of North America, Bill can't possibly have been waiving his right to sue me for copyright infringment - there is no infringement inherent in such an act, and thus there is no cause of action for a copyright suit. Therefore, the only thing he could possibly have been waiving was his right to revoke my license. QED.
No, it wasn't.

Yes there is, because he put a reflection of the ITAR regulations in the license. There would be no copyright issue if the license didn't mention where you could use the software. But it does, so there is.
