Nullification is where a state has a right to disagree with a federal law they think is unconstitutional and not correct, and no longer abide by it. Nullification would have weakened the Union because states would no longer have to agree or act on certain laws, causing obvious conflict within the state and conflict between Congress and the state. The state would no longer be unified and a quarrel between people in the state, the states, and between the state and the Congress would deepen and would most likely lead to war and weaken the Union.
No, I believe that multiple weaknesses in the Articles of Confederation would have hurt America in time. One of the biggest problems was the lack of detail and specific attributes that the Constitution brings from long discussion and debates over what is best for the country. America needed to strengthen it's central government if it wanted to get anywhere, so we may not have become so powerful if we left the majority of the power in the state's hands. Another lacking component was the fact that we had no Executive branch to enforce Congress' laws and no National court to determine the meaning of the laws. Another example is the making of one currency for the entire country. These examples and more could have hurt America if they wouldn't have written the Constitution.
I believe it's camelot. Sorry if I'm wrong.
