- Marihuana and Dangerous drugs
1. Full documentation on the Marihuana and Dangerous Drug Task Force has been pouched (register no. 19128) and will arrive in your hands shortly.
2. Above documentation contains information on so-called “Operation Intercept” which will be full-fledged U.S. effort along entire U.S.-Mexican border to interrupt traffic of drugs and marihuana from Mexico.
3. As security precaution approximate dates for “Operation Intercept” are omitted from reference material. However, for your information only, it is anticipated that operation will commence between September 15 and September 30 and last for approximately one month. It is unlikely that logistics involved can be arranged prior to earlier date and it is highly undesirable, for variety of reasons, postpone operation later than September 30.
4. We are aware of possible negative implications of operation on proposed meeting of Presidents and we are desirous avoiding, [Page 2] to extent possible, unpleasant incidents at meeting which could be caused by unusually stringent border crossing inspections, etc.
5. After you have had opportunity study Task Force documentation, we would appreciate views on following questions, as well as any other considerations you wish to raise:
A. Effect, from point of view Mexican sensitivities, of holding meeting while “intercept” under way. If this highly undesirable, would relations be damaged should “intercept” commence within several days after meeting?
B. Task Force willing give 24–48 hours advance notice of “intercept” to selected high GOM officials. Additional advance time not possible because of high risk of leaks and consequent loss of surprise factor. We would appreciate your views on best means informing GOM of purpose of operation and at same time assuring GOM that it in no way affects very cordial relations between our countries.
