After the telegram was fully decrypted, the British were eager to send it to America. However, they soon reached an impasse. There were two options, to send it publicly or privately, but both ways had its own risks. If the British dispatched the message openly to America, Germany may suspect that British cracked their code and change their codebooks. Britain would lose the many years it had taken them to have a copy. If the British sent the message confidentially, it would prove that they had engaged themselves into the America’s diplomatic communication system and would form mistrust between the two countries. In patience for a new way, Admiral Hall waited to see the America’s response to Germany’s unrestricted submarine warfare before sending the telegram immediately after the decryption, Admiral Hall waited to see the America’s response to Germany’s Unrestricted Submarine Warfare. But as America kept its neutrality even after one-month of USW, the British knew they had to send the telegram in some way or another without getting noticed by the Germany and without revealing the fact that they spied on America’s private telegraph.
The British showed their intelligence once more as they thought of a solution to their deadlock. They remembered that a copy of the telegram was sent out to Mexico from the German Embassy in Washington. Therefore, a copy would still remain in one of the public telegraph office in Mexico City. Then the British, with the excuse that they got hold of the telegram by spying on Mexico, can send the message to the American government without any troubles. Luckily, a British agent known as Mr. H was able to attain a copy. After, the Mexican copy was handed to British Foreign Minister, Arthur James Balfour, who passed it onto Walter Page, an American Ambassador in Britain. Walter Page drafted the version that was sent to the President Woodrow Wilson. On February 23, 1917, the final, decoded Zimmermann Telegram reached the hands of the President.
