It serves us right if we don't arrest the signatories. We have the evidence. This is worse cowardice on the part of the administration than when Nixon was too afraid to arrest the Pentagon Papers guy...so he pathetically allowed the "plumbers" to go after the guy's medical records. Why not be direct this time? Arrest any American signatories. Put others on an international watch list.
You've got it. That is what we need to do.
