Why did Washington act so quickly with military action against this rebellion?

Washington acted quickly with military action against the Whiskey Rebellion to assert federal authority and demonstrate that the government would enforce its laws. The rebellion posed a significant challenge to the newly established federal government’s ability to levy taxes, which was essential for its legitimacy and functioning. By responding decisively, Washington aimed to prevent the spread of dissent and maintain order, reinforcing the principle that violent resistance to Federal Laws would not be tolerated. This swift action helped solidify the federal government's power and set a precedent for handling future insurrections.
