A "paper tiger" is a term used to describe something or someone that appears powerful, threatening, or influential but is actually weak, ineffectual, or incapable of withstanding challenge. The phrase originates from a Chinese expression (zhǐlǎohǔ) and was popularized internationally by Mao Zedong, who used it metaphorically to describe imperialism and political opponents that seemed strong but were fundamentally powerless. Essentially, a paper tiger looks intimidating like a real tiger but lacks the substance or strength behind the appearance.
The term is often applied in politics, organizations, or situations where the outward show of power does not translate into actual power or results.
