I believe the correct answer was/is "He wants to mobilize America to prepare for war, just in case."
Explanation:
While Adams was president, he help prevent a full on war with France. The French were upset because the U.S. would not repay their debts to the new French government. Once the French heard about the peace treaty between the U.S and Great Britain they became infuriated. Out of anger they began seizing and pirating U.S ships. As more problems increased with the French, including the large payments they demanded before negotiation Americas became angry and upset. Though most Americans wanted war, John Adams worried that the U.S was too young and its military was too small to go to war again. But just in case of war he sent fellow officers or high ranked Americans to discuss peace with the French, while he continued to improve their military...just in case of war.
