Step-by-step explanation:
The Articles of Confederation heavily limited the government's power. As a result, they were unable to collect taxes to fund a federal military that could enforce their laws on the states. Since the government was so weak under the Articles of Confederation, the states could do as they pleased, ignoring the federal laws and fighting amongst themselves about laws such as state borders. The lack of federal power and military created a weak nation that foreign countries could easily exploit.
