Those Germans classed as minor and lesser offenders and followers were barred from any public office and had their civic privileges withdrawn; they could not run businesses, practice professions, teach or hold formal positions. The purpose of this was was not retributive. It was, very clearly, to get Nazis out of the way and keep them out of the way to allow ordinary, democratic Germans to take up public offices and civic positions and 'crowd out' any remaining Nazi influence in German society. One could re-write the original allied de-nazification directive to be relevant to today's threat:-
(1) To liberate our people from Islamicism and Jihadism, and to secure a lasting base for democratic national life in peace with the world, all those who have actively supported the Islamicist hatefulness, or are guilty of having violated the principles of justice and humanity, or of having selfishly exploited the conditions thus created, shall be excluded from influence in public, economic and cultural life and shall be bound to make reparations.
(2) Everyone who is responsible shall be called to account. At the same time he shall be afforded opportunity to vindicate himself
In Germany, the vast majority of adjudged offenders were dealt with by means of a fine. A third of that number had their employment restricted, a smaller number had property confiscated and the smallest number were permanently ineligible to hold public office. The vast, the greatest, majority were exhonerated - and and I expect the same would apply to Muslims in Britain today.
