As someone who has orchestrated two coups in different organizations, where the leadership did not align with the organization's interests and missions, I can assure you that the final stage of such a coup is not something that can be executed after just an hour of preparation or thought. It requires months of planning. The trigger is only pulled when there is sufficient evidence or justification for such action. Building support for a coup takes time and must be justified by a pattern of behavior from your opponent, not just a single action. Extensive backchanneling and one-on-one discussions are necessary to gauge where others stand, share your perspective, demonstrate how the person in question is acting against the organization's interests, and seek their support. Initially, this support is not for the coup, but rather to ensure alignment of views. Then, when something significant happens, everything is already in place. You've been waiting for that one decisive action to pull the trigger, which is why everything then unfolds so quickly.
