At the height of the Suez crisis, Adenauer visited Paris to meet the French Premier Guy Mollet in a show of moral support for France. The day before Adenauer arrived in Paris, the Soviet Premier Nikolai Bulganin sent the so-called "Bulganin letters" to the leaders of Britain, France, and Israel threatening nuclear strikes if they did not end the war against Egypt. The news of the "Bulganin letters" reached Adenauer mid-way on the train trip to Paris. The threat of a Soviet nuclear strike that could destroy Paris at any moment added considerably to the tension of the summit. The Paris summit helped to strengthen the bond between Adenauer and the French, who saw themselves as fellow European powers living in a world dominated by Washington and Moscow.
