George Kennan's Long Telegram and the Strategy That Won the Cold War

In Washington, a memo longer than one page is treated as a hostile act. A telegram of roughly 8,000 words, sent in the middle of a winter night from a freezing embassy on the other side of the world, ought to have been filed under "later," then "never." Instead it changed the course of the twentieth century.

That is the story of George Kennan's Long Telegram, which landed in the State Department on February 22, 1946, and is the closest thing American foreign policy has to a founding text of the Cold War. Whatever you think of Kennan, and conservatives have had mixed feelings about him for seventy years, the idea he put on paper is the reason that the Soviet Union's long contest with the West ended without a nuclear exchange. Let me tell you how it happened, who argued about it, and what a patient strategy toward Moscow still has to teach us.

The man in the cold embassy

Kennan was a career diplomat, a Foreign Service officer who had spent years learning Russian and studying Russia. In early 1946 he was the number-two man in the American embassy in Moscow, and in the ambassador's absence he was running the shop. The Second World War was over by only months. The wartime alliance with Stalin's Soviet Union, a marriage of convenience, was falling apart in plain sight.

Two things happened that winter. On February 9, 1946 Stalin delivered a speech in Moscow that many in Washington read as a declaration that peace with the capitalist world was impossible. And around the same time, the Treasury Department in Washington sent the embassy a puzzled query: why was the Soviet government so reluctant to join the new International Monetary Fund and World Bank? Officials wanted an explanation.

Kennan seized the chance to answer a bigger question than the one asked. He answered it with a telegram so long that it had to be sent in five parts. It was not a reply to a Treasury request. It was an anatomy of the Soviet regime.

What the telegram said

Strip off the diplomatic politeness and the Long Telegram makes a set of claims.

1. Soviet hostility came from the regime's insecurity, not from anything the West had done. The Soviet leadership, Kennan wrote, needed an outside enemy to justify its own rule at home. The conflict was not a misunderstanding that could be cleared up over dinner. It was built into the system.
2. Soviet power was not suicidal. Moscow was patient and opportunistic, and it advanced where it met weakness. But it was not reckless. It would retreat when it met strong resistance.
3. Reasoning would not move it. Force would. Kennan said the Soviet leadership was impervious to the logic of reason and highly sensitive to the logic of force. That sentence is the heart of the document.
4. The West should respond with firmness and confidence, and by getting its own house in order. The United States should be healthy at home, a model that others wanted to follow, and should not panic.

That last point gets forgotten. Kennan's real remedy was not a war. It was strength, steadiness and the avoidance of hysteria.

Why did it land so hard? Because Washington was hungry for an explanation. The telegram gave policymakers a coherent picture of an adversary they had been struggling to understand, and it came from a man who had actually read the Soviet press and sat in the rooms. Within weeks it was circulating among the senior leadership of the government. Secretary of the Navy James Forrestal had it reproduced and passed around. Kennan, the junior diplomat who wrote it, was suddenly famous inside the building.

"X" in Foreign Affairs

The ideas needed a public face. In July 1947 Foreign Affairs, the journal of the Council on Foreign Relations, published an essay called "The Sources of Soviet Conduct." It was signed "X." Everybody inside the foreign-policy world soon knew who "X" was, and the secret did not last long.

The essay recast the telegram for a general audience and gave us the word that defined the era. The United States, Kennan argued, should pursue a policy of "long-term, patient but firm and vigilant containment" of Russian expansive tendencies. Containment: stop Moscow from expanding, and wait. His bet was that the Soviet system carried within it the causes of its own decay. Hold the line, he said, and over time the regime would either mellow or break up.

Hold that thought, because it was a prediction. In 1947 it sounded almost absurdly optimistic. In December 1991, forty-four years later, the Soviet Union dissolved. Kennan's patience was vindicated, and the people who mocked it should have the decency to blush.

From idea to policy: the Truman Doctrine and NSC-68

An idea is cheap until somebody funds it. The funding arrived in 1947.

On March 12, 1947 President Harry Truman went before Congress to ask for $400 million in aid for Greece and Turkey, which were under pressure from communist insurgency and Soviet demands. He said that it must be the policy of the United States to support free peoples resisting subjugation by armed minorities or outside pressure. That is the Truman Doctrine. Congress, which at that point had a Republican majority, approved the aid in May.

A few months later came the Marshall Plan, which rebuilt Western Europe's economies on the theory that hunger and ruin are a gift to communist parties. We covered the Republican role in that in Trade Is Foreign Policy and Every President Has Treated It That Way. Then in 1949 came the North Atlantic Treaty, the founding of NATO, the alliance whose famous Article 5 says an attack on one is an attack on all. See The One Time NATO's Article 5 Was Invoked, and Who Answered the Call for how that promise was finally tested.

And in April 1950 a document known as NSC-68, drafted by the State and Defense departments under the guidance of Paul Nitze, who had succeeded Kennan as head of the Policy Planning Staff, called for a big increase in American military strength to contain Soviet power. Truman approved it that fall after the Korean War began. NSC-68 is where containment grew a lot more muscle than its author had intended.

Kennan's quarrel with his own idea

Here is the twist that makes the story interesting. Kennan spent much of the rest of his life arguing that people had misread him.

His argument was that containment had been meant as a political and economic strategy, not mainly a military one. He thought the real contest was for the allegiance and prosperity of Europe and Japan, the great industrial centres. He did not believe the Soviets were planning to invade Western Europe, and he worried that putting the emphasis on armies and arms races would make Moscow more paranoid, harder to deal with, and less likely to evolve. He was uneasy about NSC-68 and about how the military side of containment came to dominate.

In 1997, long after the Cold War, he also wrote that expanding NATO eastward would be a mistake. That is a view you can accept or reject, and many people, including most conservatives, reject it. The countries of Central and Eastern Europe wanted in, for reasons they understood far better than any retired diplomat. I would simply say that anyone who wants to cite Kennan as an authority has to take all of him, not just the parts that suit the argument.

So who was right? Here's my verdict. Kennan was right about the diagnosis and right about the timeline. He was too quick to dismiss the role of military strength, and the facts of the Berlin blockade of 1948 and 1949, the Korean War and the Soviet nuclear test of 1949 show why Truman felt the need for armed deterrence behind the political strategy. The military backbone was not a betrayal of containment. It was the part of containment that made the patient part possible. As our post on Peace Through Strength Is Older Than Reagan and It Still Works argues, the idea that strength keeps the peace is much older than any one president.

When containment was stretched too far

A good idea becomes a bad one when it is applied to everything. Containment eventually turned into a reflex: wherever a communist movement appeared, someone in Washington declared it the next domino. The strategy that Kennan designed for the great industrial centres of Europe and Asia was being used to justify commitments in places he considered peripheral.

The sharpest example is Vietnam. Kennan testified before the Senate Foreign Relations Committee in February 1966 and urged caution about the war, saying in effect that it was not a vital interest of the kind containment had been designed to protect. You can believe the war was justified or not. Conservatives disagree about it to this day. But the lesson from Kennan's testimony is a useful one for anyone who wants to use the word "containment" in an argument: a strategy that treats every spot on the map as equally vital is not a strategy. It is a mood.

Choosing priorities is what strategy means. A country with finite money, finite soldiers and finite attention has to say where it will stand and where it will not. The honest version of that sentence is uncomfortable, which is why politicians avoid it, and why Kennan's insistence on it still stings.

The conservative critique of containment

I would be doing you a disservice if I told this as a tale in which everyone agrees. Republicans have argued with containment from the beginning, and the best objection deserves to be stated fairly.

The critique says: containment is passive. It accepts that communist regimes will remain in place for as long as it takes, and that the people living under them will wait. It treats a moral wrong, the imprisonment of hundreds of millions of people behind the Iron Curtain, as a fact of geography. In the 1952 campaign, Republicans attacked the Truman administration's policy as negative and defeatist, and John Foster Dulles, who would become Eisenhower's Secretary of State, spoke of "liberation" instead.

That criticism has real force. But look at what happened. When Hungarians rose up in 1956, no American rescue came, because the alternative was a direct clash with a nuclear power. The rhetoric of liberation was easier to say than to do. It took a different mix of pressure, economics and diplomacy in the 1980s to get beyond containment, which is the story told in How the Reagan Doctrine Turned Containment Into Rollback. And it was precisely the foundation of containment, the alliances and the strong economies it protected, that gave Reagan something to build on. Containment and rollback were not opposites. One was the platform for the other. You can read the argument about who deserves the credit in Did Reagan Really Win the Cold War or Did the Soviets Just Collapse.

What a patient strategy still teaches

Now to the point of telling all this. You do not need a telegram to apply the lessons, and I would offer five.

1. Understand the other side's domestic politics. Kennan's greatest insight was that foreign behaviour often comes from the needs of a regime at home. Know what the leadership needs and fears before you decide how to deal with it.
2. Strength is a precondition of diplomacy. Talk when you hold a hand worth playing. A conversation from weakness is a request.
3. Alliances multiply power. Containment worked because it was never a solo act. NATO, Japan and the economies of Western Europe carried weight Washington could not have carried alone.
4. Strategic patience is not passivity. It is a plan with a long horizon, and it requires the political stamina to sustain it through four decades and nine presidents of both parties, Truman through the elder Bush. That is the hard part in a democracy.
5. Do not mirror-image the adversary. The Soviet Union was not America with a different flag. Assuming your opponent thinks like you is the oldest mistake in diplomacy.

For a modern application, look at how arguments over aid, sanctions and security guarantees to Eastern Europe keep returning to these themes. Our post What America Promised Ukraine in 1994 and What It Did Not shows how important it is to read the actual words of a commitment before leaning on it, and Hawks, Restrainers, Realists and Nationalists on the Right, Compared sets out how the factions of the right would apply the lessons differently.

The bottom line

• The Long Telegram of February 22, 1946, and the "X" article of July 1947, gave America a strategy for an adversary it did not understand: contain it, be patient, and wait for its internal contradictions to do their work.
• The strategy was vindicated when the Soviet Union dissolved in 1991, but it succeeded because it was backed by alliances, a strong economy and a credible military.
• Kennan was right about the diagnosis and the timeline and wrong to downplay the military side. Read all of him, not just the convenient parts.
• The best conservative critique, that containment alone accepts injustice, has force, and the answer in the 1980s was to build on containment, not discard it.
• When a politician promises a quick fix with Moscow or anyone else, ask whether he has a plan that survives nine presidents. That is the test containment set.
