This change would be significant because it consolidated power within the central government, strengthening its authority over the states. It allowed for a more unified and cohesive defense system for the entire country, instead of relying on individual state militias. It also addressed the weaknesses in the Articles of Confederation, which lacked a central military force and struggled to respond effectively to threats. Overall, this change helped establish a more centralized and organized government structure, promoting stability and security for the newly formed United States.
