Lately, there’s been a lot of rhetoric comparing Donald Trump to Adolf Hitler. The concern is that a Nazi-type regime may be rising in America.

That process, however, began a long time ago.

In fact, as historian Robert Gellately recounts, following the second World War, the U.S. government recruited Hitler’s employees, adopted his protocols, embraced his mindset about law and order, implemented his tactics in incremental steps, and began to lay the foundations for the rise of the Fourth Reich.

Sounds far-fetched? Read on. It’s all documented.

With every passing day, the United States government borrows yet another leaf from Nazi Germany’s playbook: Secret police. Secret courts. Secret government agencies.

Surveillance. Censorship. Intimidation. Harassment. Torture. Brutality. Widespread corruption. Entrapment. Indoctrination. Indefinite detention.

These are not tactics used by constitutional republics, where the rule of law and the rights of the citizenry reign supreme.

Rather, they are the hallmarks of authoritarian regimes, where the only law that counts comes in the form of heavy-handed, unilateral dictates from a supreme ruler who uses a secret police to control the populace.

That danger is now posed by the FBI, whose laundry list of crimes against the American people includes surveillance, disinformation, blackmail, entrapment, intimidation tactics, harassment and indoctrination, governmental overreach, abuse, misconduct, trespassing, enabling criminal activity, and damaging private property, and that’s just based on what we know.

Consider the FBI’s far-reaching powers to surveil, detain, interrogate, investigate, prosecute, punish, police and generally act as a law unto themselves—much like their Nazi cousins, the Gestapo—and then try to convince yourself that the United States is still a constitutional republic.

Just like the Gestapo, the FBI has vast resources, vast investigatory powers, and vast discretion to determine who is an enemy of the state.

Today, the FBI employs more than 35,000 individuals and operates more than 56 field offices in major cities across the U.S., as well as 400 resident agencies in smaller towns, and more than 50 international offices. In addition to a “data campus,” which houses more than 96 million sets of fingerprints from across the United States and elsewhere, the FBI has also built a vast databases on Americans that are not only being added to and used by local police agencies, but are also being made available to employers for real-time background checks.

All of this is made possible by the agency’s nearly unlimited resources (its minimum budget alone in fiscal year 2015 was $8.3 billion), the government’s vast arsenal of technology, the interconnectedness of government intelligence agencies, and information sharing through fusion centers.

Much like the Gestapo spied on mail and phone calls, FBI agents have carte blanche access to the citizenry’s most personal information.

The FBI has access to every piece of mail that passes through the postal system.

Moreover, the agency’s National Security Letters allows the FBI to secretly demand that banks, phone companies, and other businesses provide them with customer information and not disclose those demands to the customer.

Much like the Gestapo’s sophisticated surveillance programs, the FBI’s spying capabilities can delve into Americans’ most intimate details (and allow local police to do so, as well).

In addition to technology (which is shared with police agencies) that allows them to listen in on phone calls, read emails and text messages, and monitor web activities, the FBI’s surveillance boasts an invasive collection of spy tools. Law enforcement agencies are also using social media tracking software to monitor Facebook, Twitter and Instagram posts.

Moreover, secret FBI rules also allow agents to spy on journalists without significant judicial oversight.

Much like the Gestapo’s power to render anyone an enemy of the state, the FBI has the power to label anyone a domestic terrorist.

As part of the government’s so-called ongoing war on terror, the nation’s de facto secret police force has begun using the terms “anti-government,” “extremist” and “terrorist” interchangeably. Moreover, the government continues to add to its growing list of characteristics that can be used to identify an individual (especially anyone who disagrees with the government) as a potential domestic terrorist.

Much like the Gestapo infiltrated communities in order to spy on the German citizenry, the FBI routinely infiltrates political and religious groups, as well as businesses.

As Cora Currier writes for the Intercept: “Using loopholes it has kept secret for years, the FBI can in certain circumstances bypass its own rules in order to send undercover agents or informants into political and religious organizations, as well as schools, clubs, and businesses.” The FBI has even been paying Geek Squad technicians at Best Buy to spy on customers’ computers without a warrant.

Just as the Gestapo united and militarized Germany’s police forces into a national police force, America’s police forces have largely been federalized and turned into a national police force.

In addition to government programs that provide the nation’s police forces with military equipment and training, the FBI also operates a National Academy that trains thousands of police chiefs every year and indoctrinates them into an agency mindset that advocates the use of surveillance technology and information sharing between local, state, federal, and international agencies.

Just as the Gestapo’s secret files on political leaders were used to intimidate and coerce, the FBI’s files on anyone suspected of “anti-government” sentiment have been similarly abused.

As countless documents make clear, the FBI has no qualms about using its extensive powers in order to blackmail politicians, spy on celebrities and high-ranking government officials, and intimidate and attempt to discredit dissidents of all stripes.

When and if a true history of the FBI is ever written, it will not only track the rise of the American police state but it will also chart the decline of freedom in America, in much the same way that the empowerment of Germany’s secret police tracked with the rise of the Nazi regime.

How did the Gestapo become the terror of the Third Reich?

It did so by creating a sophisticated surveillance and law enforcement system that relied for its success on the cooperation of the military, the police, the intelligence community, neighborhood watchdogs, government workers for the post office and railroads, ordinary civil servants, and a nation of snitches inclined to report “rumors, deviant behavior, or even just loose talk.”

In other words, ordinary citizens helped create the monster that became Nazi Germany “not through active collaboration but through passivity, denial and indifference.”

Much like the German people, “we the people” have become passive, polarized, gullible, easily manipulated, and lacking in critical thinking skills.

Distracted by entertainment spectacles, politics and screen devices, we too are complicit, silent partners in creating a police state similar to the terror practiced by former regimes.
