Did the constitution resolve the weaknesses in the articles of confederation?

Yes. Under the Articles of Confederation, the government couldn’t control trade. With the Constitution, the government could control interstate trade. With the Articles of Confederation, there was no President. Instead, a weak three-person committee ran the government. This was done because people were afraid one person might abuse his power like the King had done. With the Constitution, there was a person, called the President, who had power and ran the government.

Militarism is the answer.
