two groups of Democrats Irreconcilables and the Reservationists
The Irreconcilables refused to join the League of Nations under all circumstances
The Reservationists argued that the Treaty needed to be heavily amended to coincide with US policy
agreed that this principle of collective security forfeited the powers of the US government to the League Council.
Wilson was unwilling to compromise and refused to negotiate with Lodge on the principles of the League.
The Consequences
League became guardian of status quo
Collective security was ineffective without universal involvement of all nations
Did not enforce the Treaty of Versailles
Because Germany and Russia were excluded, caused heightened tensions between Eastern and western Europe- led to Treaty of Rapallo (1922)
USA rejection of League diminished its prestige
Remaining countries had to enforce treaty without the aid of powerful America
Great Britain began to resort to isolationism- canceled Anglo American guarantee to support France
Many nations dropped out of league between 1919-1939 after USA rejection

In 1945 the Soviet Union most positively,and the United States most probably, would not have ratified the charterif it had in fact authorized the method of collective security.
