Antifa is modeled after groups that took part in the chaos of the 1920s and 1930s German Weimar Republic.

Would they use the same methods? Would they put on police uniforms and work to divide us?

"The Gleiwitz incident was a part of a larger operation carried out by Abwehr and SS forces.[5] Other orchestrated incidents were conducted along the Polish-German border at the same time as the Gleiwitz attack, such as a house burning in the Polish Corridor and spurious propaganda. The project was called Operation Himmler and comprised incidents giving the appearance of Polish aggression against Germany.[10][8] German newspapers and politicians, including Adolf Hitler, had made accusations against Polish authorities for months before the 1939 invasion of organising or tolerating violent ethnic cleansing of ethnic Germans living in Poland.[10][11] On 1 September 1939, the day following the Gleiwitz attack, Germany launched Fall Weiss (Case White), the invasion of Poland, which precipitated World War II in Europe. Hitler cited the border incidents in a speech in the Reichstag on the same day, with three of them called very serious, as justification for his invasion of Poland.[10] Hitler had told his generals on 22 August, "I will provide a propagandistic casus belli. Its credibility doesn't matter. The victor will not be asked whether he told the truth".[5][8]"
