Final answer:
Power is the capacity to impose one's will on others and it permeates political, social, and personal domains. It can be institutionalized through laws or customs and has been historically demonstrated by nations like the US in international contexts. Power also influences our attitudes and behaviors both internally and externally.
Step-by-step explanation:
Power is a key concept in politics and can be defined as the ability to exercise one's will over others. This can manifest through various forms such as rational-legal authority, where power is legitimized by rules, regulations, and laws, or through traditional authority, based on long-standing customs. Power affects social groups, organizations, and especially governments, both in controlling their own citizens and influencing other nation-states.
Historically, the US has demonstrated its power internationally through efforts like forming the Allied forces during World War II, the invasion of Iraq in 2002, and the imposition of sanctions on North Korea. Additionally, power influences attitudes and behaviors through internal mechanisms like cognitive dissonance and external factors such as authority and advertisements.
