Final answer:
George Washington would likely have had reservations about NATO based on his advice in his farewell address, as it goes against the principle of avoiding permanent alliances.
Step-by-step explanation:
Based on George Washington's advice in his farewell address, it is likely that he would have had reservations about NATO. Washington emphasized the importance of avoiding permanent alliances and instead focusing on good faith, justice, peace, and harmony with all nations. NATO, as a military alliance, goes against the principle of avoiding entanglements in foreign conflicts. While Washington supported friendly trade relations, he warned against political alliances that could drag the young nation into Europe's imperial wars.
