What historical figure's advice is referenced in the senator's argument against foreign alliances?

The correct choice cites George Washington's perspectives on foreign alliances, particularly his warning against the dangers of entangling alliances with foreign nations. In his Farewell Address, Washington advised that the United States should avoid permanent alliances, as they could lead to conflicts that do not serve the nation's interests. His belief underscored the importance of independence and caution in foreign policy, advocating for a pragmatic approach that prioritized national sovereignty and the nation's well-being over international commitments. This historical context provides a foundation for why a senator might invoke Washington’s advice when arguing against foreign alliances, as it aligns with a long-standing sentiment in American political thought.
