This is quite well established. Nazi party membership was huge and trying to vet former Nazi's post-war while there wasn't enough food to go around was pretty quickly dropped. In person interviews at the start became "this guy says he never did anything wrong and hates the Nazi party now". "DeNazified" papers were just rubber stamped at that point. After the war, it was pretty much the UK who fought the hardest to "de-Nazify" the new Germany - from high level all the way down to anyone who had a smug of blood on their hands. France was eager at first, but drama at home (and lack of funds for the occupation) made them drop the idea pretty quickly. Plus they had their own "cleansing" immediately after liberation so quenched their thirst for vengeance pretty early on. Americans were focused on a strong Western Germany to counter the USSR. The centuries old European bad blood meant nothing to them, so once they skim off the worst of the Nazi's it was more about creating a functioning country. Russia made a good showing at first, but like the Americans realized "the juice wasn't worth the squeeze" and if faced with a choice of "we can't fill this important position" and "we can just fill it with a low level Nazi who pinky promises not to do it again", the chose the 2nd option. Eventually the UK gave up as well. They just held out the longest.
