Workers World Party is a 1956 split from the Trotskyist Socialist Workers Party that formed because they felt the SWP was not defending the USSR's invasion of Hungary. Since they, their ideology has been that any dictator will be praised, as long as they are an opponent of the US; the WWP has been a cheerleader for regimes ranging from North Korea to Iraq to Milosevic's Serbia to China's actions at Tiannemen. Along with their politics, there practice has been to create "unity" coalition dominated by the sect, which are used to prevent real democratic coalitions.
