DELIBERATE CONFIDENCE? OR MENTAL INSTABILITY?

SPOILER WARNING: This essay contains major spoilers for Season 4 of Netflix’s The Diplomat, including significant plot developments, presidential decisions, and events in the season finale.

The fourth season of Netflix’s The Diplomat presents an American president whose increasingly aggressive decisions alarm her advisers, threaten longstanding alliances, and eventually provoke an extraordinary rebellion within her own administration. President Grace Penn, portrayed by Allison Janney, is intelligent, experienced, politically formidable, and convinced of the necessity of her decisions. Her confidence is unmistakable. Her judgment becomes the central concern. The series forces a distinction between a president who deliberately accepts enormous risks because she trusts herself and a president whose judgment has become unstable enough that she can no longer reliably evaluate those risks.

The distinction is important because the consequences of presidential decisions do not depend exclusively on the president’s intentions. They depend on the decisions themselves, the authority used to implement them, and the willingness of other officials to participate. American history has already demonstrated the importance of that last consideration. On October 20, 1973, President Richard Nixon ordered the dismissal of Watergate special prosecutor Archibald Cox. Attorney General Elliot Richardson refused and resigned. Deputy Attorney General William Ruckelshaus also refused and was removed. Solicitor General Robert Bork ultimately carried out the order. The episode became known as the Saturday Night Massacre. Its significance extended beyond Nixon’s conduct to the very different responses of the officials asked to execute his wishes.

More than fifty years later, The Diplomat examines a remarkably similar institutional problem.

Grace Penn survives an assassination attempt early in Season 4. Her behavior subsequently changes. She becomes more confrontational, more willing to threaten military force, and less receptive to restraint. Her administration has secretly seized a Russian nuclear weapon from a disabled submarine near Britain. When the British government takes steps that could expose the operation, Penn threatens to send American warships into British waters. Her ambassador, Kate Wyler, recognizes the potential consequences and attempts to moderate the message. Penn responds by escalating the confrontation.

The uncertainty surrounding Penn is intentional. Series creator Debora Cahn has explained that the people surrounding the president struggle to determine whether the circumstances have changed her or whether something within her has changed. Janney has described a president who begins doubting her own instincts but responds by asserting herself even more forcefully. The resulting behavior becomes increasingly alarming to those closest to her.

This is where deliberate confidence and mental instability become competing explanations. A president exercising calculated confidence may understand the consequences and accept them. A president experiencing unstable judgment may respond disproportionately to events, disregard essential information, or lose the consistency required to make consequential decisions. The outward behavior may look similar. The implications for those responsible for carrying out presidential instructions are considerably different.

The people surrounding Grace Penn initially continue trying to make the administration function. They reinterpret her conduct, moderate her instructions, and search for explanations that allow them to continue serving. Deputy Chief of Mission Stuart Hayford formally objects through the State Department’s dissent channel and is recalled to Washington. Kate attempts to prevent a confrontation with Britain. Vice President Hal Wyler remains deeply involved in the administration’s decisions. White House Chief of Staff Billie Appiah continues trying to manage a president whose judgment she increasingly questions.

Eventually, at the G7 summit, Penn publicly threatens countries that interfere with the American military operation. Kate resigns in front of the assembled leaders. Billie and Secretary of State Miguel Ganon follow her. Hal subsequently joins them.

The dramatic significance lies in how much the administration accommodated before those resignations occurred. The officials recognized individual warning signs long before they collectively withdrew their cooperation.

For Americans watching in October 2026, the fictional crisis unfolds against the documented conduct of President Donald Trump.

On February 18, 2025, Trump signed an executive order titled Ensuring Accountability for All Agencies. It expanded presidential supervision over independent regulatory agencies and directed that the president and attorney general provide controlling legal interpretations for executive branch employees acting in their official capacities. The administration defended the measure as necessary to establish democratic accountability and ensure consistent execution of federal law. Its implications for the independence of regulatory decision-making were substantial.

On June 3, 2026, the White House announced another executive order implementing Schedule Policy/Career, affecting approximately 8,000 policy-influencing federal positions. The administration characterized the change as a means of removing employees for misconduct, poor performance, or failure to implement lawful presidential directives. Its accompanying description also confirmed that affected employees would serve in at-will positions.

These decisions establish something important about the actual presidency. Trump has used formal executive authority to change the relationship between presidential leadership and the officials responsible for implementing federal policy. The resulting structure gives presidential supervision a larger role in determining how government agencies operate.

That structure matters enormously when presidential decisions become controversial.

In June 2025, Trump federalized thousands of California National Guard troops following demonstrations in Los Angeles. California challenged the deployment. On October 23, 2026, the United States Court of Appeals for the Ninth Circuit affirmed a preliminary injunction directing the federal government to return control of the Guard to Governor Gavin Newsom. The administration had asserted authority to use federalized troops to protect federal personnel and property. The litigation tested the statutory limits of that authority.

The dispute concerned more than competing political positions. It involved the circumstances under which presidential orders could place state military forces under federal control. The courts were required to examine the legality of presidential action after the executive branch had already taken substantial steps to implement it.

Another example emerged from Trump’s March 6, 2025, executive order targeting the law firm Perkins Coie. The order directed federal officials to impose restrictions involving security clearances, government contracts, and access to federal facilities. On May 2, 2025, a federal district court ruled against the order and granted permanent injunctive relief. The court found constitutional violations arising from the government’s treatment of the firm. The administration challenged the ruling.

Trump also exercised his constitutional pardon authority on January 20, 2025, to commute specified sentences and grant broad pardons to people convicted of offenses related to January 6, 2021. The proclamation additionally directed the attorney general to pursue dismissal of pending indictments involving those events. The president described the action as correcting an injustice. Its practical consequence was to eliminate or reduce criminal penalties across a substantial category of cases arising from the attack on the Capitol.

Each decision involved identifiable presidential authority. Each also required other people and institutions to implement, defend, review, or challenge the president’s instructions.

That is precisely why The Diplomat deserves attention beyond its portrayal of Grace Penn.

The central institutional issue is not resolved by determining whether a president possesses extraordinary confidence or unstable judgment. Public officials remain responsible for their own conduct. A legally questionable instruction does not become lawful because it originates in the Oval Office. Nor does an official’s disagreement with presidential policy automatically establish misconduct. The Constitution, federal statutes, judicial rulings, and the official’s actual responsibilities determine the relevant boundaries.

There is a compelling reason to hope that members of the Trump administration watch The Diplomat, particularly its fourth season.

They would encounter a fictional administration in which accomplished officials repeatedly explain, accommodate, and attempt to manage presidential decisions that increasingly trouble them. They would see the consequences of treating each new controversy as an isolated event. They would also see what happens when officials conclude that continued participation carries responsibilities they can no longer reconcile with their duties.

The series cannot establish that any particular member of the Trump administration would respond similarly. It can, however, present circumstances that invite serious examination of the obligations accompanying public office.

The oath prescribed for federal civil officers under 5 U.S.C. § 3331 requires them to support and defend the Constitution. It does not establish personal allegiance to the president as the measure of faithful public service.

The broader problem may be that repeated exposure to presidential controversies has altered what audiences find extraordinary. A fictional president threatens military confrontation with an ally, and the program expects viewers to recognize the seriousness of the threat. A fictional administration struggles with obedience, professional responsibility, and dissent, while Americans have watched actual disputes over presidential authority proceed through executive orders, federal agencies, and the courts.

The show’s most consequential warning may therefore concern the people who continue serving when the president’s conduct becomes increasingly difficult to defend.

Grace Penn’s advisers eventually reach a point at which they refuse to continue. Their decision does not erase their earlier participation or resolve the international crisis they helped create. It establishes that they have finally accepted responsibility for their own conduct.

That responsibility exists long before a crisis reaches its breaking point.

Whether presidential behavior reflects deliberate confidence or unstable judgment, those entrusted with public authority must answer for the decisions they make in response. In The Diplomat, the final episode makes that responsibility impossible to ignore.

In the United States, it was never supposed to require a television finale.
