Answer:
Option b. Supporting democratic change
Explanation:
In the hypothetical case in which one of the United State's allies is in danger of coming under a communist dictatorship, and the dictator does not have a track record of forcing violence against its citizens, the United States has the possibility of taking military action against the dictator with the premise of supporting democratic change. AS the leader of the free world, the United States held the international role of assuring and fighting in order to promote democracy everywhere in the planet. So in the case that there would be a dictator threatening to change a once democratic country into a communist dictatorship, the United States could get involved military and would probably had the support of its citizens and the international community.
