paper tiger

The phrase "paper tiger" refers to something or someone that appears strong, threatening, or powerful, but is actually weak, powerless, or ineffective. It is often used metaphorically to describe an entity or an individual who puts on a show of strength, but lacks substance or the ability to follow through on their threats or promises. The term originated from the Chinese phrase "zhilaohu" and was popularized by Mao Zedong to criticize political opponents who seemed formidable but lacked true power.
