What Was The Waterloo Scandal?

Not Waterloo.  LOL!!!  (that was Napoleon)

 WATERGATE.  (US President Richard Nixon)

Watergate was the nickname given to a series of political scandals that originated (during the Richard Nixon administration)with the illegal breaking and entering into offices of the Democratic National Convention HQ in Washington DC during June 1972.  The entire affair and crimes termed "Watergate" included  campaign fraud, political espionage, sabotage, illegal break-ins,  questionable tax audits, illegal wiretapping,  and a secret slush fund to pay those who conducted these operations. This secret fund
was also used to buy silence of the seven men who were
indicted for the DNC break-in

There is no scandal that called The Waterloo Scandal, however sometimes any particular scandal may be compared to Waterloo.  This is in reference to the battle of Waterloo in which Napoleon was decisively defeated. If a single scandal totally ruins the career of a politician or celebrity it may be considered a Waterloo scandal or simply their Waterloo.

Consider this example: www.newser.com

It is entitled: Ethics Scandal is No Waterloo for Palin. It then goes on to describe how her career will not be ended by this scandal. It is not a Waterloo scandal for her because it will not finish her off.

That was not Waterloo - that was called Watergate and involved police spying.
