When you have a number of choices to select from, use a list or a chart. Draw a circle or a semi-circle with a radius of about 4 - 6. Mark the choices off as degrees on the circle. Hold the pendulum in the center and the swing of the pendulum will line-up with the appropriate marked off selection.
April 24, 1965 - President Johnson announces Americans in Vietnam are eligible for combat pay. May 3, 1965 - The first U.S. Army combat troops, 3500 men of the 173rd Airborne Brigade, arrive in Vietnam.
That doesnât always apply, of course, since the two Presidentâs who presided over the ill-advised war in Vietnam both served in the military during World War II, and that didnât seem to prevent either Richard Nixon or Lyndon Johnson from making decision about the war that seem to be quite foolhardy in retrospect.
