What weakness did delegate at the constitutional convention see in the articles of confederation

A weak central government

Explanation:

The Articles of Confederation was the first US Constitution that was replaced by the current Constitution. The Articles of Confederation were written before America went into the American Revolution War, it aimed to create a united country at the same time that the colonies remained independent.

The problem was that the Articles created a weak central government, that did not have many powers which caused the lack of united leadership since the country did not have a strong representative of other countries.

The Central government did not have the power to tax, so to have money the Central government should ask for loans of foreign governments or relay on the will of the states to give it money.

The Central government also was unable to gather a combined military force as a Union.
