On Sunday, 22 June 1941, Hitler broke the Molotov-Ribbentrop pact by invading the Soviet Union. Coincident with the invasion, Cordell Hull delivered another amendment of the draft on understanding to the Japanese, but this time there was no recognition of the Japanese right to control of Manchukuo, the new draft also completely rejected the Japanese right of military expansion in the Pacific. Hull included a statement which in summary said that as long as Japan was allied to Hitler an agreement would be next to impossible to achieve. He did not specifically mention Matsuoka, but it was implied that he would have to be removed, as the foreign minister was now advocating an immediate attack on the Soviet Union, and did so directly to the emperor. Konoe was forced to apologize to the emperor and assure him that Japan was not about to go to war with the Soviet Union. Masanobu Tsuji had planned to assassinate Konoe if peace had occurred with the United States in order for Japan to attack the Soviet Union, who was at war with Japan's ally Germany.
