In the governmental structure created by our Constitution, the Executive is endowed with enormous power in the two related areas of national defense and international relations. This power, largely unchecked by the Legislative1 and Judicial2 branches, has been pressed to the very hilt since the advent of the nuclear missile age. For better or for worse, the simple fact is that a *728President of the United States possesses vastly greater constitutional independence in these two vital areas of power than does, say, a prime minister of a country with a parliamentary form of government.
In' the absence of the governmental checks and balances present in other areas of our national life, the only effective restraint upon executive policy and power in the areas of national defense and international affairs may lie in an enlightened citizenry — in an informed arid critical public opinion which alone can here protect the values of democratic government. For this reason, it is perhaps here that a press that is alert, aware, and free most vitally serves the basic purpose of the First Amendment. For without an informed and free press there cannot be an enlightened people. ~
Yet it .is elementary that the successful conduct of international diplomacy and the maintenance of an effective national defense require both confidentiality and secrecy. Other nations can hardly deal with this Nation in an atmosphere of mutual trust unless they can be assured that their confidences will be kept. And within our own executive departments, the development of cori-sidered and intelligent international policies would be impossible if those charged with their formulation could not communicate with each other freely, frankly, and in confidence. In the area of basic national defense the frequent need for absolute secrecy is, of course, self-evident.
I think there can be but one answer to this dilemma, if dilemma it be. The responsibility must be where the power is.3 If the Constitution gives the Executive *729a large degree of unshared power in. the conduct of foreign affairs and the maintenance of our national defense, then under the Constitution the Executive must have the largely unshared duty to determine and preserve the degree of internal security necessary to exercise that power successfully. It is an awesome responsibility, requiring judgment and wisdom of a high order. I should suppose that moral, political, and practical considerations would dictate that a very first principle of that wisdom would be an insistence upon avoiding secrecy for its own sake. For when everything is classified, then nothing is classified, and the system becomes one to be disregarded by the cynical or the careless, and to be manipulated by those intent on self-protection or self-promotion. I should suppose, in short, that the hallmark of a truly effective internal security system would be the maximum possible disclosure, recognizing that secrecy can best be preserved only when credibility is truly maintained. But be that as it may, it is dear to me that it is the constitutional duty of the Executive— as a matter of sovereign prerogative and not as a matter of law as the courts know law — through the promulgation and enforcement of executive regulations, to protect *730the confidentiality necessary to carry out .its responsibilities in the fields of international relations and national defense.
This is not to say that Congress and the courts have no role to play. Undoubtedly Congress has the power to enact specific and appropriate criminal laws to protect government property and preserve government secrets. Congress has passed such laws, and several of them are of very colorable relevance to the apparent circumstances of these cases. And if a criminal prosecution is instituted, it will be the responsibility of the courts to decide the applicability of the criminal law under which the charge, is brought. Moreover, if Congress should pass a specific law authorizing civil proceedings in this field, the courts would likewise have the duty to decide the constitutionality of such a law as well as its applicability to the facts proved.
But in the cases before us we are asked neither to construe specific regulations nor to apply specific laws. We are asked, instead, to perform a function that the Constitution gave to the Executive; not the Judiciary. We are asked, quite simply, to prevent the publication by two newspapers of material that the Executive Branch insists should not, in the national interest, be published. I am convinced that the Executive is correct with respect to some of the documents involved. But:I cannot say that disclosure of any of them will surely result in direct, immediate, and irreparable damage to our Nation or its people. That being so, there can under the First Amendment be but one judicial resolution of the issues before us. I join the judgments of the Court.
The President’s power to make treaties and to appoint ambassadors is, of course, limited by the requirement of Art. II, § 2, of the Constitution that he obtain the advice and consent of the Senate. Article I, § 8, empowers Congress to “raise and support Armies,” and “provide and maintain a Navy.” And, of course, Congress alone can declare war. This power was last exercised almost 30 years ago at the inception of World War II. Since the end of that war in 1945, the Armed Forces of the United States have suffered approximately half a million casualties in various parts of the world.

“It is quite apparent that if, in the maintenance of our international relations, embarrassment — perhaps serious embarrassment— is to be avoided and success for our aims achieved, congressional legislation which is to be made effective through negotiation and inquiry within the international field must often accord to the President a degree of discretion and freedom from statutory restriction which *729would not be admissible were domestic affairs alone involved. Moreover, he, not Congress, has the better opportunity of knowing the conditions which prevail in foreign countries, and especially is this true in time of war. He has his confidential sources of information.. He has his. agents in the form of diplomatic, consular and other officials. Secrecy in respect of information gathered by them may be- highly necessary, and the premature disclosure of it productive of harmful results. Indeed, so clearly is this true that the first President refused to accede to a request to lay before the House of Representatives the instructions, correspondence and documents relating to the negotiation of the Jay Treaty — a refusal the wisdom of which was recognized by the House itself and has never since been doubted. . . .” United States v.
