Question

What is the main goal of u.s. foreign policy makers when a military action is less concerned with changing a nation's policies than with deposing its leaders?

Answer 1

I believe the answer is: regime change

regime change effort is often initiated if the leader does not possess the characteristics that would benefit united states. This includes things such as having different principles, unfavorable economized arrangement, the leader imposing direct threats to the general well-being of other nations etc.
