Final answer:
It is false that the governor of Florida can develop U.S. foreign policy towards Cuba; this power is reserved for the federal government.
Step-by-step explanation:
The assertion that the governor of Florida has the constitutional authority to develop official U.S. foreign policy towards Cuba is false. Under the U.S. Constitution, the development and implementation of foreign policy are powers that belong exclusively to the federal government. While Florida's geographical proximity to Cuba and the presence of a large Cuban-American population give the state significant interest in U.S.-Cuba relations, the authority for conducting foreign policy lies with the President and the U.S. Congress. Furthermore, such matters are often informed by historical U.S. interests in Cuba, including economic dominance, security implications under the Monroe Doctrine, and geographic strategy.
