The United States would have been much weaker as a result. In addition, civil rights and liberties would likely not have ever been adopted due to the requirements that 100% of the states had to agree to amendments before they took effect (compared to three-fourths in the Constitution). In addition, the standing in the world would likely have been weaker due to the constant fighting between the northern states, which were more manufacturing-based and the south, which was more agrarian.
