Final answer:
President George W. Bush was not a proponent of liberal internationalism; rather, his foreign policy is better characterized as neoconservative with an emphasis on using military power unilaterally to promote national interests.
Step-by-step explanation:
The statement that President George W. Bush was a proponent of liberal internationalism in his foreign policy is false. President Bush is often associated with a foreign policy philosophy known as neoconservatism, which emphasizes the use of American military power to promote democracy and protect national interests, particularly after the events of September 11, 2001. This approach can be seen in instances such as the invasion of Iraq in 2003. Liberal internationalism, on the other hand, typically favors multilateral institutions and agreements, international law, and cooperative security arrangements, contrasting with the unilateral actions that were characteristic of the Bush administration's policies.
