Was it necessary or right to drop the Articles of Confederation for the Constituition?

Answer 1

According to the Articles, Congress had power to regulate foreign affairs, war, and the postal service and to appoint military officers, control Indian affairs, borrow money, determine the value of coin, and issue bills of credit.

However, the Articles gave the Congress no power to enforce its requests to the states for money or troops, and by the end of 1786 governmental effectiveness had broken down, and a new more efficient system was required.

Answer 2

It wasn't necessary and whether it was right or not is in th eeye of the beholder. For the positive side read the "Federalist Papers" and for the negative side read the "Anti-Federalist Papers."
