During the Cold War, the paper was central to exposing numerous war crimes and atrocities, including publishing proof that British soldiers were decapitating people in Malaya, publishing evidence of the USA's use of biological weapons during the Korean War, and revealing the existence of mass graves of civilians killed by the South Korean government. The "Morning Star" has survived numerous attempts at censorship, being banned by all British wholesalers for nearly 12 years, being the victim of police raids and politically motivated libel suits, being banned by the UK government between 1941-1942, and threats by the British government to have its journalists tried for treason and executed. Despite these difficulties, the paper has lasted to become the longest-running socialist newspaper in British history.
