One of the weakest parts of the Articles of Confederation was its lack of provisions for a strong central government. The Articles of Confederation established a loose confederation of states, in which the national government had limited powers and the states retained a great deal of autonomy. This decentralized structure made it difficult for the national government to effectively address the challenges facing the newly-formed United States, such as ensuring the security of the country and managing its finances.
The lack of a strong central government under the Articles of Confederation was evident in several ways. For example, the national government had no power to regulate commerce or collect taxes, which made it difficult to fund its operations and pay its debts. In addition, the national government had no power to enforce its decisions, which meant that states could ignore federal laws and policies if they chose to do so. This lack of effective national power made it difficult for the United States to respond to domestic and foreign challenges, and contributed to the eventual adoption of the Constitution, which established a stronger central government.
Overall, the lack of a strong central government was a major weakness of the Articles of Confederation, and was one of the key factors that led to its eventual replacement by the Constitution. This weakness made it difficult for the United States to effectively address the challenges it faced as a young nation, and highlighted the need for a more powerful and centralized national government.
