Is that what the website and your reading assignment say?

The difficulty for Congress in fulfilling its duties under the Articles of Confederation can be attributed to several reasons. One reason is that Congress lacked the power to regulate foreign trade. This meant that individual states could implement their own trade policies, leading to economic competition and barriers between states. As a result, Congress was unable to effectively negotiate trade agreements with other countries or establish a consistent national trade policy.

Another reason is that most congressional decisions required the approval of at least nine out of the thirteen states. This made it challenging to pass legislation and make important decisions, as it was often difficult to gather enough states' support. Each state had its own interests and priorities, which made it hard to reach a consensus on key issues.

Additionally, under the Articles of Confederation, any congressional action required the executive approval. This meant that the president had considerable influence over congressional decisions, making the legislative process more cumbersome and prone to delays or blockades.

Lastly, Congress lacked the power to declare war. This limited its ability to effectively defend the nation and address threats to its security. It required the unanimous agreement of all thirteen states to declare war, making it nearly impossible to respond quickly and decisively in times of conflict.

Overall, the lack of central authority and limited powers granted to Congress under the Articles of Confederation hindered its ability to fulfill its duties effectively and efficiently.
