The three commanders of Brazil's armed forces abruptly resigned yesterday, following President Jair Bolsonaro's ousting of the defense minister on Monday. The shakeup has fueled rampant speculation about a breakdown in Bolsonaro's relationship with the military, a key part of the president's political alliance. Analysts expressed fears that Bolsonaro, who is increasingly unpopular and under political pressure, was moving to assert greater control over the military.
