(MENAFN- The Rio Times) Argentina's president Javier Milei has just changed the people in charge of the country's muscle: security and defense.

On paper it looks like a routine reshuffle. In reality, it opens an old wound and redraws the balance between politicians, generals and street power.

From 10 December, Alejandra Monteoliva will take over as security minister, replacing Patricia Bullrich.

Luis Petri will leave the Defense Ministry for Congress, and Army chief Lieutenant General Carlos Alberto Presti will step in as defense minister. Milei keeps the same line, but gives it new faces.

Monteoliva is not a newcomer. She has been running day-to-day security as national secretary, pushing a firm stance against drug gangs, organized crime and roadblocks.

She worked for years on security projects in Colombia and once handled a police revolt and looting crisis as security minister in Córdoba province.

Her mission now is simple: keep backing the police, keep the streets open, and show visible results.


Milei's Security Shake-Up Puts A General In Charge Of Argentina's Defense
Presti's promotion is the real shock. He is a career officer, born in 1966, who led elite airborne troops, headed the military academy and served in Argentina's peacekeeping mission in Haiti.

As army chief since early 2024, he pushed a generational change by sending many older generals into retirement.

Now he becomes the first active-duty general to run the Defense Ministry since the end of military rule in 1983.

For Milei and many voters tired of insecurity, this looks like long overdue normalisation. They argue that the armed forces have paid for the dictatorship for forty years, while drug cartels, violent protests and crumbling infrastructure spread.

Putting a respected officer in charge of defense, they say, treats the military as part of the solution, not the problem.

Opponents see something darker. Presti's late father was an officer accused of crimes during the dictatorship.

Human-rights groups fear that giving a general a political ministry, and tightening rules on protests at the same time, could quietly weaken civilian control and the culture of accountability.

For observer and investors, the message is clear: Argentina is betting on more order and a bigger role for its uniformed institutions.

Whether that brings stability or new clashes will shape the country's climate for business, politics and public life in the years ahead.
