Of the 248 vetoes recorded by the five permanent Security Council members since the inception of the United Nations, the United States, as of 2001, has cast 73. (29%... as there are five members with veto, 20% would be a completely even distribution. There were no US vetos before 1970) 38 of those were to sheild Israel from UN-SC "action".
On November 29, 1947, the General Assembly of the United Nations adopted, with a 2/3 majority, a plan to partition western Palestine into a Jewish and an Arab state. The plan was put forth by a committee consisting of representatvies of Canada, Czechoslovakia, Guatemala, Netherlands, Peru, Sweden, and Uruguay.
So does that mean that the US has, by way of those 38 vetoes, protected the integrity of a UN-GA resolution?
