Why Do Citizens Play a Smaller Role in the Formation

Why do citizens play a smaller role in the formation of foreign policy than they do in the formation of domestic policy?

A) Foreign policy is more complex and unpredictable than domestic policy, and during a crisis, the need for speed and secrecy may exclude the public from decision making.
B) Foreign policy is handled only by the Department of State, which keeps most of its operations confidential.
C) Domestic policy concerns American citizens, but foreign policy has little effect on them, so there is no need for their input.
D) The Constitution gives most foreign policy responsibilities and powers to Congress, so ordinary citizens as well as the president and executive branch are excluded from most decisions.
E) In crisis situations, the president's actions often come under criticism from the public, causing great dissent, so it is prudent for the president to share as little as possible with the public during a crisis.
