January 5, 1973

Dear Mr. President:

This will acknowledge your letter of December 20, 1972.

There is nothing substantial that I can add to my many previous messages, including my December 17 letter, which clearly stated my opinions and intentions. With respect to the question of North Vietnamese troops, we will again present your views to the Communists as we have done vigorously at every ether opportunity in the negotiations. The result is certain to be once more the rejection of our position. We have explained to you repeatedly why we believe the problem of North Vietnamese troops is manageable under the agreement, and I see no reason to repeat all the arguments.
