Final answer:
Jefferson justified making enemies with the British because of their abuses of power and their impact on American sovereignty and rights, such as unreasonable taxes, trade interference, and impressment of sailors, leading to foreign policy challenges during his presidency.
Step-by-step explanation:
Thomas Jefferson justified making enemies of the British due to numerous injustices imposed by the British monarchy. This included taxing colonists without representation, interfering in trade, denying trial by jury, and preventing self-government. With the signing of the Declaration of Independence, Jefferson and the founders committed to a new vision of governance, distinct from British tyranny.
Foreign Pressures during Jefferson's presidency, such as the Napoleonic Wars, risked the neutrality of the United States. Jefferson faced challenges like British impressment of American sailors, adding to the enmity towards Great Britain. Jefferson's avoidance of military conflict through measures like the Embargo Act of 1807, which aimed to use economic pressure to combat British and French violations of American shipping rights, demonstrated his commitment to diplomacy over warfare, despite its limited success.
