There are many perfect examples in our recent history which undoubtedly show that dictatorial regimes impose subjection, blackmail, servitude, intimidation, abuse, persecution and execution upon innocent people. However, many Americans are strongly convinced and assuredly assert that such a thing could never happen in the United States. But is this just desirous reasoning?
Or, is there something essentially disparate about the United States that makes it resistant to the despotic abuse that has afflicted every other considerable empire in history? The primary step in scrutinizing the assertion that it can't happen here is to recognize and describe what "IT" is. Many people have distorted, almost comic-book-type, impression of dictatorship.
In the real world autocracy has always crept in under the pretense of safeguarding the nation, defending the people, and establishing law and order. A dictator, in order to acquire and hold power, must demand the support of the people. An effective oppressor cannot publicly display malevolence and desire for power but must design his approach so as to persuade the people that his goals are righteous, that he wants honesty and fairness to abound, and that the most desirable way to make that true is to give him or her dominance and authority.
Tyrannical governments develop by abusing people's fears - economic uncertainty, crime, foreign aggressors and so on and persuading the people that the quick-fix is for a political leader to be legally given absolute jurisdiction so he can shield the people from the wickedness of the world. This is always the pattern out of which autocracy is born.
No matter how cruel or bloodthirsty regime becomes those in charge will persist to claim noble intentions and will dictate that an extreme government powers are required to protect the people and to create justice and order. Every time mankind has taken a step away from democracy and towards autocracy it was done in the name of defending the country and the people.
