In the next year the influence of Roosevelt's personality was again felt in affairs outside the traditional realm of American international interests. Germany was attempting to intrude in Morocco, where France by common consent had been the dominant foreign influence. The rattling of the Potsdam saber was threatening the tranquillity of the status quo. A conference of eleven European powers and the United States was held at Algeciras to readjust the treaty provisions for the protection of foreigners in the decadent Moroccan empire. In the words of a historian of America's foreign relations, "Although the United States was of all perhaps the least directly interested in the subject matter of dispute, and might appropriately have held aloof from the meeting altogether, its representatives were among the most influential of all, and it was largely owing to their sane and irenic influence that in the end a treaty was amicably made and signed." * But there was something behind all this. A quiet conference had taken place one day in the remote city of Washington. The President of the United States and the French Ambassador had discussed the approaching meeting at Algeciras. There was a single danger-point in the impending negotiations. The French must find a way around it. The Ambassador had come to the right man. He went out with a few words scratched on a card in the ragged Roosevelt handwriting containing a proposal for a solution. ** The proposal went to Paris, then to Morocco. The solution was adopted by the conference, and the Hohenzollern menace to the peace of the world was averted for the moment. Once more Roosevelt had shown how being wise in time was the sure way to peace. * Willie Fletcher Johnson, "America's Foreign Relations", vol. II, p. 376. ** The author had this story direct from Mr. Roosevelt himself. Roosevelt's most important single achievement as President of the United States was the building of the Panama Canal. The preliminary steps which he took in order to make its building possible have been, of all his executive acts, the most consistently and vigorously criticized.
