There is doubt that America's vital interests are sufficiently threatened in Vietnam to necessitate the growing commitment there.

There is doubt that such vital interests as may be threatened are best protected by this growing commitment.

There is doubt that a war which may devastate much of the countryside can lead to the stable and prosperous Vietnam we once hoped our presence would help create.

There is considerable concern about apparent contradictions in the American position on certain points basic to any efforts to negotiate a settlement. High Government officials reiterate our eagerness to negotiate "unconditionally," but we remain unclear about our willingness to accept full participation by the Vietcong as an independent party to negotiations.

Similarly, Administration spokesmen reiterate our commitment to self-determination for South Vietnam, but we remain unclear about our willingness to accept a coalition (or pro-Communist) government should the people of South Vietnam eventually choose such a government under adequate international supervision.

Finally, Mr. President, we must report a growing sense -- reinforced by Mr. Harrison Salisbury's recent reports from Hanoi -- that too often there is a wide disparity between American statements about Vietnam and American actions there.

We hope you will find it possible to share your thoughts with us about these matters. The rising confusion about national purpose can undermine mutual trust and respect among our people. This seems to us as urgent a problem as any that confronts the nation today.

We are grateful for your interest and send our best wishes for the New Year
