Final answer:
The claim that President George W. Bush was a proponent of liberal internationalism is false; his foreign policy was more closely aligned with unilateralism and neoconservative ideals.
Step-by-step explanation:
The statement that President George W. Bush was a proponent of liberal internationalism in his foreign policy is false. George W. Bush's foreign policy was often characterized by unilateralism and neoconservative principles, which included a willingness to act without international support if necessary, a strong emphasis on national security, and the promotion of democracy through foreign interventions. This approach differs significantly from liberal internationalism, which is characterized by a strong preference for multilateralism, cooperation with international institutions, and a focus on economic, social, and diplomatic efforts over military solutions.
