Domestic policy includes all of the following issues EXCEPT

a. public education.
b. adult health care.
c. protection against poverty.
d. the implications of war.
e. child health care.

To determine the answer to this question, we need to understand what domestic policy is and then assess each option to see if it aligns with the definition.

Domestic policy refers to government decisions and actions that primarily focus on issues, problems, and concerns within a country's national borders. It encompasses various areas, such as public education, healthcare, poverty reduction, and social welfare.

Let's evaluate each option:

a. Public education: This is an example of a domestic policy issue as it deals with the education system within the country. Therefore, this option is included in domestic policy.

b. Adult health care: Healthcare policies are typically part of domestic policy, as they address the well-being and medical needs of individuals within a nation. Therefore, this option should also be included in domestic policy.

c. Protection against poverty: Policies designed to address poverty and provide assistance to those in need are an important aspect of domestic policy. Hence, this option should be included.

d. The implications of war: This option mentions the implications of war, which generally falls under the domain of foreign or international policy, rather than domestic policy. Therefore, this option could be the correct answer.

e. Child health care: Similar to adult health care, policies concerning the healthcare of children would typically be considered part of domestic policy. Hence, this option should also be included.

Based on the analysis, it appears that the correct answer to the question is option d. The implications of war, as it does not directly relate to domestic policies but rather falls within the realm of foreign policy.
