[CW] What collaboration with the Nazi regime during, shortly before and slightly after WWII in MENAT+Osman Empire happened?

I did read some threads today and hit this answer by u/commiespaceinvader in which (and the one after)it is said, that there was collaboration with the Nazis in the MENAT/+Osman Empire during WWII.

I am interested in that collaboration, especially for what is now Israel and surrounds it, as well as Northern Africa.

How much was cooperation in helping the crimes of the Shoa and genocide of the Nazis that was done by the regimes/governments in the countries or the population basically on their own accord/voluntarily? What role did play antisemitism in that? What degree was coerced and how much did the elites of the countries try to follow through with those coercions?

The other main thing I would be interested in is: what were results after the Nazis very defeated (or pushed back out of the countries mentioned) in the region mentioned? Was it safe instantly? Was there compensation, were there truth and reconciliation commissions? Was there violence even after Germany was defeated? How was dealt with large scale crimes, was talk about it forbidden, or the deeds denied, the victims not acknowledged? Were there repercussions for the willing helpers?

I know that operation T4 for example targeted people for ableist reasons and the ideology of the Nazis, were other groups of the Shoa and Holocaust and Porajmos etc. also victims of collaboration in those countries mentioned?
