Mm...
How had this Haneda Yu Ze quietly become the leader of Kusagakure? And at the time, Kusagakure's leader had been a rather famous ninja, with considerable strength and prestige.

Gently setting down the letter of appointment, the Third Hokage picked up the pipe beside him and took a light puff. His brows furrowed ever tighter, and his expression grew increasingly grave.
Clearly, if this had been a coup, then it could only have taken place around the time the Land of Grass closed itself off.
Yet while the Land of Grass had closed itself off, it had remained open to Konoha. That was likely to dispel the suspicions of Konoha and the other ninja villages that sought to win Kusagakure over, which was why it had not completely shut itself off.
It could be said that closing itself off had cut off interference from all outside forces, such as the major ninja villages. Otherwise, with the interference of major ninja villages, the coup would likely have become a prolonged struggle. The former leader's faction would have sought help from other great nations and major ninja villages, and so long as they offered solid, practical alliances—such as lower tariffs, reduced hiring fees, or a certain percentage of mission kickbacks—the great nations and major ninja villages would certainly have helped the former leader's faction without hesitation.
