Final answer:
Both parties in a relationship may possess a degree of power over each other, which can vary depending on context and factors. Power is not just personal but also affects groups and nations, evidenced by U.S. interventions abroad and governmental power balance regarding foreign policy and the necessary and proper clause.
Step-by-step explanation:
The statement in question is a matter of perspective and context. Generally, in any relationship, both parties may have some degree of power over the other; this can be true in interpersonal relationships, social groups, or between nations. Power dynamics are complex and can be influenced by numerous factors, including social status, economic resources, and cultural norms.
In the context of international relations, power can be exercised in various ways, such as military intervention, economic sanctions, or diplomacy. The United States government, for instance, has a history of using its influence to affect other countries, be it through forming alliances, engaging in warfare, or implementing sanctions.
Power dynamics are also present within a government's structure. For instance, the necessary and proper clause in the Constitution, contrary to the assertion in question, has often been interpreted to extend the powers of the national government rather than to limit them.
Similarly, the division of foreign policy powers between the president and Congress is an example of a balance within the governmental power structure. Meanwhile, the experiences of individuals in times of crisis, such as the burdens faced by many women during wars, demonstrate the manifestation of power in social settings and historical moments.
