Who said 'From a country that once roared like lions for freedom we now blather like sheep for protection'?

Norman Vincent Peale (see related link). The correct quote is:

"Once we roared like lions for liberty; now we bleat like sheep for security! The solution for America's problem is not in terms of big government, but it is in big men over whom nobody stands in control but God."

I've also seen it as:

Americans used to roar like lions for liberty, now we bleat like sheep for security.
