On March 17, 1917, President Wilson met with his Cabinet to consider the question of whether the US should enter the Great War. Fortunately for historians of this period, Secretary of State Robert Lansing drafted a detailed memorandum of the meeting:
The Cabinet Meeting of today I consider the most momentous and therefore, the most historic of any of those which have been held since I became Secretary of State, since it involved, unless a miracle occurs the question of war with Germany and the abandonment of the policy of neutrality which has been pursued for two years and a half….
The corridors of the State Department and Executive Office swarmed with press correspondents seeking to get some inkling of what would be done from passing officials. It was through these eager crowds of news-gatherers that I forced my way at half-past two Tuesday afternoon under a bombardment of questions, to which I made no reply, and entered the Cabinet room where all the other members had arrived.
Three minutes later the President came in and passed to his place at the head of the table shaking hands with each member and smiling as genially and composedly as if nothing of importance was to be considered. Composure is a marked characteristic of the President. Nothing ruffles the calmness of his manner or address. It has a sobering effect on all who sit with him in council. Excitement would seem very much out of place at the Cabinet table with Woodrow Wilson presiding.
