Final answer:
St. Thomas Aquinas laid out three conditions for a just war, but agreement with these conditions is subjective. His writings may have influenced Thomas Jefferson and Martin Luther King indirectly.
Step-by-step explanation:
St. Thomas Aquinas laid out three conditions for a just war: the war must be declared by a legitimate authority, the cause must be just, and the intentions must be good. These conditions have been influential in shaping the understanding of just war theory. However, whether one agrees with them or not is subjective and dependent on personal beliefs and perspectives.
The writings of St. Thomas Aquinas may have had an indirect influence on Thomas Jefferson and Martin Luther King. Aquinas' emphasis on natural law and the inherent dignity of all human beings may have contributed to the ideas of equality and individual rights that were foundational to the American Revolution and the Civil Rights Movement.
