U.S. President Donald Trump has replaced the heads of the two core departments he backed most strongly, barely a year into his second administration. Kristi Noem, who led the Department of Homeland Security, stepped down on the 5th of last month. Then Pam Bondi, who led the Ministry of Justice, was dismissed on the 2nd local time. The two were key figures who stood at the forefront of large-scale immigration crackdowns and Trump-style governance. In other words, it means that even the department heads Trump empowered most can be changed at any time when performance issues, controversy, and political burdens pile up.

On the 2nd, President Trump fired Minister Bondi and named Todd Blanche, a former personal criminal defense attorney for Trump, as acting attorney general in her place. The Ministry of Justice is the agency that serves as a solid legal shield, conducting all-out investigations targeting Trump's political opponents while defending against various legal challenges from outside forces aimed at the administration.

Bondi, who was ousted, had led the Ministry of Justice since February last year. During her tenure, she shook the ministry with a large-scale personnel overhaul and investigations targeting political opponents, braving criticism that she was undermining independence. However, the release of documents related to Jeffrey Epstein ended without substance, contrary to the preview of a "bombshell," drawing backlash from both parties. Bondi herself faced pressure from the House Oversight Committee to comply with a subpoena.

Cases targeting former FBI Director James Comey, New York Attorney General Letitia James, and others that Trump had hoped for were also repeatedly halted in court over procedural issues. As a result, Bondi roiled the Ministry of Justice but failed to persuade the judiciary. Reuters noted that "the backlash spread not only to Democrats but also to resistance within pro-Trump ranks," calling Bondi a political failure.

For former Minister Noem, practical ineptitude ultimately proved her undoing. The Department of Homeland Security serves as the key execution hub overseeing the mass deportation of millions of undocumented immigrants and the construction of border barriers. Noem faced criticism for excessively concentrating decision-making authority in the minister's office as she pushed a hard-line immigration stance too forcefully. This led to side effects such as delays in budget execution and disaster response operations. The fallout from the fatal shooting of a federal agent in Minneapolis and a border enforcement ad contract that cost $220 million (about 330 billion won) also generated massive political expense.

The new heads set to lead the departments are expected to chart a clearly different course from their predecessors. Merlin, tapped to succeed Noem and sworn in as Homeland Security minister, immediately scrapped the complicated direct-approval rules the predecessor had put in place. Citing experts, Reuters assessed that this move shows a strong will to keep the Trump administration's existing immigration policy line intact while executing it more practically and efficiently.

At the same time as Bondi's dismissal on the 2nd, Blanche, nominated as her successor in an acting capacity, is a closest legal representative who exclusively handled President Trump's personal criminal cases. The Guardian analyzed that appointing Blanche is a strategic gambit by Trump to tighten his grip on the Ministry of Justice. The assessment is that, rather than people who merely shout blind loyalty, he is refilling the core of power with manager-type figures who can actually control the departments and prove tangible results in a short time.

This method of immediately replacing even core confidants when political burdens grow or results lag aligns with the extreme performance-first approach Trump showed when he ran corporations in the past. Running a giant real estate corporation, he gained public recognition as the host of the popular TV program "The Apprentice," where he would angrily tell executives and contestants who fell short of targets, "You're fired!"

President Trump transplanted this corporation-style personnel management method directly into the top echelons of U.S. government power. Even a minister who fails to meet what the president demands is treated like an executive who failed to deliver shareholder value and must be ready to pack up at any time. Human resources expert John Sullivan said, "Trump's management style places absolute emphasis on promising immediate and significant outcomes to all stakeholders," adding, "Members of the organization must deliver results, and if they do not, they are quickly exited from the organization."

Trump's sweeping personnel shake-up is unlikely to stop with the dismissal of two ministers and may well spread across the Cabinet. In Washington political circles, Defense Minister Pete Hegseth is being closely watched as the next likely replacement target. President Trump has recently been pressing Hegseth hard with heavy responsibility for the full-scale military operation against Iran.

On the 23rd of last month, at an Air National Guard event in Memphis, Tennessee, President Trump said that "Minister Hegseth was the first to advocate for war with Iran." Because of this, there is speculation that if he fails to deliver eye-catching results that quickly secure clear military superiority and force the Iranian regime into complete submission, Hegseth could also be dismissed like the other two.
