In October 1989, at the beginning of round three of the CFE negotiations, both NATO and the WTO presented (tabled) proposals for information exchanges, stabilizing measures, and verification. (See Figures 7.1 through 7.3). Both indicated an intent to insist on effective verification through measures that would include the detailed reporting of TLE quantities by unit designation and geographic location. And both proposed intrusive On-Site Inspections (OSI) at all reportable locations. Finally, each side tabled proposals to constrain activities that might be perceived as threatening to the other side. These constraints are known as stabilizing measures.
The final CFE verification regime is probably the single most important element of the round three proposals. In addition to OSI, the final regime might include monitors at storage sites (a NATO proposal) and at exit-entry points (a WTO proposal), observer teams to verify adherence to the stabilizing measures (much as is already being done under the Stockholm agreement), and remote sensors and aerial overflights (similar to the President's Open Skies proposal, which is also under consideration by NATO and the WTO). The important similarities and differences between the verification proposals tabled by NATO and those tabled by the WTO will be discussed at greater length. For now, suffice it to say that Pact insistence on continuous monitoring at exit-entry points (EEPs) could become very contentious. The other differences appear to be more negotiable.
With respect to the information exchanges and stabilizing measures, there were many similarities and few differences. There do not appear to be any "treaty- stoppers"; however, the proposed constraints on exercises, reporting requirements for transit of TLE through the ATTU region, and prior notification requirements for the call-up of reservists could present significant difficulties. These and other aspects of the proposals tabled in round three can be summarized as follows:
