Answer:
Unclear question. However I infer you are referring to US former President Richard W. Nixon.
Explanation:
His ploy was to issue a fake warning that the investigation is harmful to National Security.
Remember, the then President Nixon was under heavy investigation by the F.B.I so he warned that attempts to reveal the truth was going to endanger the country's security just to frustrate the investigations.
It depends on what you take to be the beginning and what the end. It lasted two years if you understand it as from the time it was revealed to the time Nixon resigned. It lasted 5 years if you take it from the time Nixon began doing it to the time he resigned.
