From Truman’s farewell address to the nation:

“The greatest part of the President’s job is to make decisions–big ones and small ones, dozens of them almost every day. The papers may circulate around the Government for a while but they finally reach this desk. And then, there’s no place else for them to go.
The President–whoever he is–has to decide.
He can’t pass the buck to anybody.
No one else can do the deciding for him.
That’s his job.”
