Why would the rule about needing a unanimous vote (all 13 states) to change the Articles of Confederation prove to be a terrible idea? in under 4 sentences

The requirement for a unanimous vote to change the Articles of Confederation would prove to be a terrible idea because it made it almost impossible to bring about any meaningful amendments or reforms. With 13 states, it was difficult to reach a consensus on important issues, leading to legislative gridlock and a lack of progress. This rule ultimately hindered the ability of the government to adapt and respond to changing circumstances, leading to the eventual downfall of the Articles of Confederation.
