1. A United States ship has been attacked on the high seas off North Vietnam. The Maddox quite properly repulsed the attackers and one of the attacking boats was destroyed. Now, our friends and enemies alike will await what additional moves the United States will take.

2. Refs A and B appear to be a retreat at a time when aggressive measures are necessary. Ref A now prohibits an approach by DeSoto Patrol closer than eleven miles to the North Vietnam mainland coastline. Ref B prohibits hot pursuit into hostile waters and refers to international waters parenthetically as eleven miles offshore. Does this mean that hot pursuit must stop eleven miles offshore? If so, we are drastically reducing the time and space available to our ships and aircraft for destroying the attackers.

3. Although the terms hostile waters and hostile airspace are used in the rules of engagement contained in refs C through E, no clear definition of the terms is set forth and it must be assumed that they are synonymous with territorial waters and territorial airspace of the offending country.

4. In the event of unprovoked attack, our forces should be authorized to take aggressive action to destroy the attackers. This action has traditionally included hot pursuit into the territorial waters and airspace of the hostile country. If we are to be prohibited from pursuing into territorial waters and airspace, we should be allowed to pursue to the three-mile limit where territorial waters commence, in accordance with standard U.S. policy.

5. Recommend that:

a. The terms territorial waters and airspace be used in lieu of hostile waters and airspace.

b. DeSoto Patrol be permitted to approach within eight miles of NVN coastline, thus keeping five miles clear of territorial waters.

c. Hot pursuit into territorial waters and airspace of the hostile country be authorized.

d. If hot pursuit into territorial waters is not authorized, then authorize pursuit to the three-mile limit.
