Gorbachev, Kohl, and the NATO Deal Left in a Diary
By Vera Kessler ·
For decades, the 'concrete assurances' given to the Soviet Union about NATO's expansion remained a matter of dispute, buried in the personal notes of a diplomat who saw the betrayal coming.
The collapse of the Soviet Union was not merely a failure of economics or an explosion of ethnic tension; it was a managed liquidation overseen by men who traded strategic security for the appearance of peace. Millions of citizens in Eastern Europe woke up to a world where the borders of their security had been redrawn in haste, often without their knowledge and always to the benefit of the victors.
What survives of the February 1990 negotiations is a curated archival description of a diary entry rather than the original pages, a gap that serves as a metaphor for the era's diplomacy. In these notes, Teimuraz Stepanov-Mamaladze, a Soviet official whose personal records capture the friction within the Kremlin, reflects on a moment of profound surrender. On February 10, 1990, the atmosphere in Moscow was one of frantic urgency. Helmut Kohl, the Chancellor of West Germany who had staked his career on the rapid reunification of his country, and Hans-Dietrich Genscher, the West German Foreign Minister and Vice Chancellor who had served as the Bonn Republic's primary diplomatic architect for nearly two decades, descended upon the Soviet capital.
The Haste of the Deal
According to the record, the visit was characterized by a lack of deliberation that bordered on the reckless. Stepanov-Mamaladze writes that "Kohl and Genscher paid a hasty visit to Moscow." This haste was not merely a matter of scheduling; it was a strategic weapon. By forcing a rapid tempo, the West limited the Soviet leadership's ability to consult its own military apparatus or weigh the long-term costs of its concessions.
Sharing the alarm of his superior, Eduard Shevardnadze—the final Soviet minister of foreign affairs and former governor of Georgia who viewed the end of the Cold War with a cautious, often critical, eye—Stepanov-Mamaladze notes that "just as hastily – in the opinion of E.A. [Shevardnadze] – Gorbachev accepted the right of the Germans to unity and self-determination." The record frames this not as a diplomatic triumph, but as a rush to judgment. Mikhail Gorbachev, the last leader of the Soviet Union and General Secretary of the Communist Party, had spent years attempting to pivot the state toward social democracy, but in this moment, his desire for a legacy of peace overrode the fundamental requirements of Soviet security.

Concrete Assurances and Verbal Shadows
The most damning portion of the record concerns the survival of the Soviet security architecture. The diary provides evidence that the United States and West Germany gave Moscow "concrete assurances about keeping NATO to its current size and scope." For Shevardnadze, these were not mere talking points or diplomatic platitudes. The record indicates that in Shevardnadze’s view, these assurances "amounted to a deal – which Gorbachev accepted, even while he stalled for time."
Here we find the central irony of the 1990 transition: the "concrete" nature of the assurance was entirely verbal. The public record shows that while the West was eager to secure German unity, it was equally eager to avoid any formal treaty that would legally bind NATO's future footprint. By offering "concrete assurances" in a room rather than a signed protocol, the United States and West Germany created a psychological reality for the Soviets—a sense of security—without creating a legal obligation for themselves.
Shevardnadze saw the trap. He recognized that a "deal" accepted by a leader who is "stalling for time" is not a strategic victory; it is a temporary reprieve. The line drawn between Shevardnadze's skepticism and Gorbachev's acceptance reveals a Foreign Ministry that was sounding the alarm while the General Secretary was already signing away the house. The assurances regarding NATO's size were the currency used to buy German reunification, but it was a currency that the West knew would be devalued the moment the Soviet Union ceased to exist.
The Sidelined Military
There is a void in this record that speaks louder than the words. In a discussion that fundamentally altered the strategic balance of Europe and the operational scope of NATO, the military principals of the Soviet Union are entirely absent. The diary tracks the movements of diplomats and the whims of the General Secretary, but it mentions no generals, no strategists, and no security audits.
If this file is shaped the way it looks, the desk's reading is that the Soviet military establishment was either intentionally sidelined or fundamentally ignored during the negotiation of NATO's scope. The decision to accept verbal assurances about the size of a military alliance is an act of political will, not a military calculation. No professional soldier would accept a "concrete assurance" that is not backed by a verification mechanism or a written treaty. The fact that these discussions were handled as a "hasty visit" between politicians suggests a deliberate effort to bypass the skeptics in the Ministry of Defense who would have demanded a formal guarantee.
The Lubricant of Betrayal
The pattern suggests that these "concrete assurances" served as a psychological lubricant to facilitate German unity rather than a sustainable strategic agreement. The West needed Gorbachev to feel secure enough to allow the reunification of Germany without triggering a hardline coup in Moscow. Once that objective was achieved, the assurances became irrelevant. The haste of the visit, the lack of formal documentation, and the reliance on the personal trust of a crumbling regime all point toward a calculated deception.
Furthermore, the disconnect between the Soviet leadership's public face and the Foreign Ministry's internal assessment is stark. While Gorbachev presented a front of cooperation and mutual trust, the diary of Stepanov-Mamaladze reveals a deep internal anxiety. The record shows that the people closest to the process—Shevardnadze and his staff—viewed the proceedings as insufficient and rushed. This suggests that the official Soviet record of these discussions likely omitted the internal dissent and the perceived fragility of the agreement to maintain the illusion of a unified front.
If the full, unredacted archives of this period were released, the desk's reading is that they would show a West that was actively managing Gorbachev's perceptions, feeding him just enough "concrete" language to keep him compliant while ensuring that no one in Washington or Bonn ever signed a document that would actually stop NATO's eastward march. The still-withheld pages are likely protecting the specific identities of the diplomats who crafted these verbal traps and the internal memos that dismissed the Soviet concerns as the complaints of a dying empire.
The cost of this "hasty" diplomacy was paid in the decades that followed. The pattern of verbal promises followed by strategic expansion became the blueprint for the new era. The Soviet Union was not just defeated by its own internal contradictions; it was maneuvered into a surrender by men who knew that a verbal assurance is the easiest thing in the world to break once the person who heard it is no longer in power. The tragedy of the 1990 deal is that Gorbachev believed he was negotiating a peace, when he was actually presiding over a liquidation.
