The debate over Laos, almost as intense if not as bitter as the Vietnam debate, has done more than clarify the nature of the American involvement in that patchwork kingdom which has played a secondary but significant role in the Vietnam war while also engaging in its own struggle to survive as a unitary nation. The Senate's dual actions in prohibiting the use of ground combat troops in both Laos and Thailand, and in curbing the right of the President to make a "national commitment" to any country without prior Congressional approval, have temporarily satisfied the common determination to avoid "another Vietnam." But the fundamental problem of how American policy should be made and conducted in Southeast Asia has only begun to be reëxamined.

The broad outlines of our future policy in Asia were given by President Nixon during his Asian trip last year, most fully at his preliminary stopover in Guam, but much remains hazy about the nature of our current commitments and responsibilities there. The President and other administration officials in speeches and press conferences since then have reëmphasized that, in line with reducing "our involvement and our presence" around the world, as Mr. Nixon put it in his State of the Union Message, the nations of Southeast Asia will henceforth have to bear the main burden of defending themselves against all but the most flagrant-including nuclear- forms of aggression. Still unclear and requiring further reappraisal are such substantive matters as the prerogatives of the Executive and the Departments of State and Defense to make agreements or pledges short of treaties with foreign countries without "the advice and consent" of the Senate.

Eighteen months after its enunciation at Guam the Nixon Doctrine remains obscure and contradictory in its intent and application. It is not simply that the wider pattern of war in Indochina challenges the Doctrine's promise of a lower posture in Asia. More than that, close analysis and the unfolding of events expose some basic flaws in the logic of the Administration's evolving security policy for the new decade. The Nixon Doctrine properly includes more than the declaratory policy orientation. It comprises also the revised worldwide security strategy of "1½ wars" and the new defense decision-making processes such as "fiscal guidance budgeting." These elements have received little comment, especially in their integral relation to our commitments in Asia. But the effects of this Administration's moves in these areas will shape and constrain the choices of the United States for a long time to come.
The uneasy public quiet on Vietnam which the President achieved with his speech last November 3 was shattered by the large-scale U.S. military intervention in eastern Cambodia. Once more U.S. policy in Southeast Asia became the subject of major controversy. In this situation there is some danger that we shall become so caught up in the immediate issues that we neglect more fundamental questions with respect to current American strategy. The new actions are a product of a basic fault in the structure of U.S. policy but do not, by themselves, define that fault.
As the war in Viet Nam moves well into the third year of the major phase that began early in 1965 with the deployment of large numbers of American troops, there are indications that the long and difficult conflict is in a state of irresolution, or what the communists describe as "indecisiveness." This does not mean stalemate, a word Washington officials rightly reject, since the military contest on the ground remains highly fluid and damaging to both sides, while the population and economy of North Viet Nam, subject as they are to an ever-widening pattern of bombing, are obviously being hurt (reports from the North say that half a million persons, including perhaps 100,000 Chinese, are now engaged in repairing the bomb damage). In South Viet Nam, American troops and their foreign allies, and occasionally the South Vietnamese, are continuing to win some major battles and with the help of coördinated tactical air, heavy bombing and artillery attacks are inflicting heavy casualties on the communists.
