This is ridiculous. The compulsory school attendance law was enacted by NAZI Germany. The US, Great Britain, and France - the powers occupying West Germany after WWII - should have required the constitution of the Federal Republic of Germany void all laws enacted while the NAZI’s were in power.
Should have, yes. But remember The UK was run by Labour and the US by the Democrats, who couldn’t figure out if they were “not” communist or “not” fascist.
