If you’ve spent any time scrolling through political Twitter or watching cable news over the last decade, you’ve probably seen John Brennan. He’s the guy with the gravelly voice and the intensely serious stare who became one of the most vocal critics of the Trump administration. But before he was a regular on MSNBC, he was the guy in the "vault," making decisions that literally changed the map of the Middle East.
Honestly, John Brennan is a bit of a walking contradiction. He’s a guy who once thought about being a priest—seriously, he’s talked about how he wanted to be the first American Pope—and ended up running the world’s most powerful spy agency. You’ve got people on the left who can’t forgive him for the drone strikes and the "enhanced interrogation" shadow that hangs over his early career. Then you’ve got people on the right who view him as the architect of a "deep state" plot.
But what really happened with John Brennan? Behind the talking points, there’s a 25-year career at the CIA that started with a random ad in The New York Times.
From New Jersey Altar Boy to Langley
John Brennan didn’t come from a family of spies. He grew up in North Bergen, New Jersey, the son of an Irish immigrant blacksmith. His father used to tell him never to take his American citizenship for granted. That blue-collar, Catholic upbringing in Hudson County really stuck with him. He was an altar boy, a serious student, and a guy who took the idea of "right and wrong" very literally.
In 1980, he was riding a bus to class at Fordham University when he saw a CIA recruiting ad. He had a bit of wanderlust and a desire to serve.
Basically, he just applied.
He didn't have a hook-up. He just walked into a career that would span six presidencies. Brennan wasn't just some desk jockey; he was a fluent Arabic speaker who spent years in the field. He was the CIA station chief in Riyadh, Saudi Arabia, in the late 90s. Imagine being the top American spy in the Kingdom when the Khobar Towers were bombed in 1996. That kind of experience changes a person. It makes the world look a lot more dangerous than it does from a suburban living room.
The Drone Architect and the "Terror Tuesday" Legacy
When people talk about the "former CIA director John Brennan," the conversation usually shifts to drones. It has to. During the Obama years, Brennan wasn't just the CIA Director (he took that job in 2013); he started out as the Assistant to the President for Homeland Security and Counterterrorism.
He was essentially the "drone czar."
He was the one who helped institutionalize the process of "targeted killings." Every week, there were meetings to discuss the "kill list." Critics called it "Terror Tuesday." Brennan has always defended this, arguing that using drones to take out high-level Al-Qaeda targets was the "most precise" and "humane" way to fight a war without sending in thousands of troops.
But it was messy.
There were civilian casualties. There were questions about the legal basis for killing U.S. citizens abroad, like Anwar al-Awlaki. Senator Rand Paul even famously staged a 13-hour filibuster just to get the administration to admit they wouldn't use drones on Americans on American soil. Brennan’s legacy is forever tied to this shift toward "light footprint" warfare. It's a legacy of efficiency, but also one of immense secrecy that still makes people uncomfortable today.
The Torture Controversy
One thing people often get wrong is Brennan's role in the Bush-era "enhanced interrogation" program. He wasn't the guy in the room during the waterboarding. At the time, he was the Deputy Executive Director of the CIA, and he’s since admitted he "turned his head away."
"I focused on my job and turned my head away. It's one of the things I have to live with," Brennan said years later.
He claims he privately opposed it, but he didn't stop it. This almost cost him his career. When Obama first wanted to make him CIA Director in 2008, the blowback over his ties to the Bush-era policies was so loud that he had to withdraw his name. He had to wait five years and serve in the White House before he finally got the top spot at Langley.
The Security Clearance Showdown
In 2018, things got weird. Most former CIA directors fade into the background. They join boards, write memoirs, and keep their mouths shut. Not John Brennan. He went on the offensive against Donald Trump, calling his behavior "treasonous" after the Helsinki summit with Vladimir Putin.
Trump did something unprecedented: he revoked Brennan's security clearance.
Usually, former directors keep their clearances as a "professional courtesy" so they can advise their successors. Trump argued Brennan was using his access to make "unfounded and outrageous allegations." Brennan called it an attempt to silence critics.
It was a total circus.
More than 175 former national security officials signed a letter saying the move was a threat to free speech. It turned Brennan into a hero for the "Resistance" and a villain for the MAGA movement. But beyond the politics, it raised a real question: should intelligence professionals be "political" once they leave the agency? Brennan’s take is that he couldn't stay silent when he felt the country was at risk. Others in the "company" (the CIA) think he should have stayed quiet to protect the agency’s non-partisan reputation.
What He's Doing Now (and the Alien Question)
These days, Brennan is a "Distinguished Fellow" at Fordham and a senior analyst for NBC. He’s also written a memoir called Undaunted.
But here’s a fun fact most people miss: he’s surprisingly open-minded about UFOs.
In a few interviews, he’s mentioned that some of the videos captured by Navy pilots are "eyebrow-raising." He doesn't go full "X-Files," but he’s said it’s "presumptuous and arrogant" to think there's no other form of life in the universe. It’s a weirdly human side to a guy who usually speaks in carefully parsed "intelligence-speak."
Actionable Insights: Understanding the Modern Intelligence State
If you're trying to make sense of the world Brennan helped build, here is what you actually need to know:
- The "Playbook" is Real: The drone program Brennan helped codify didn't go away. It set the precedent for how the U.S. conducts counterterrorism today.
- Intelligence is Never "Finished": Brennan’s career shows that intelligence isn't just about facts; it's about the "North Star" or moral framework you use to interpret them.
- The "Deep State" vs. Reality: While the term is used as a political weapon, Brennan’s tenure shows that there is a massive, permanent bureaucracy of career professionals who stay through different presidents. Whether that's a "shadow government" or just "career service" depends entirely on your politics.
John Brennan’s story isn't just about one guy. It’s about how the U.S. transformed from the Cold War era into the age of permanent, high-tech counterterrorism. He was there for the rise of Al-Qaeda, the hunt for Bin Laden, and the digital war with Russia. Love him or hate him, you can't tell the story of 21st-century America without him.

To really understand the current state of national security, look into the 2014 Senate Intelligence Committee report on CIA torture—it's the document that defined much of Brennan's later career and his relationship with Congress. Reading the executive summary of that report provides the necessary context for the internal battles Brennan fought at the highest levels of government.
