They accepted islam when islam was no power so forceful conversion is not possible.
About history what happened with them was really bad.
They were killed by hitler and then no european countery gave them refuge only arabs gave them refuge in palestine and then they started killing palestinians and made their own country then arabs turned against them because they were the only one who saved jews after ww2 and jews started fighting them them.
So you do not agree with the promise of judaism but you have your own promise.
And i have already told you the promise was made to children of israel (jacob).
And they are children of ashkenaz.
