This plan can be risky but it's worth considering
plan: play into the fears of the jews
whatever the jews seem to fear the most, to the point of being obsessed with it, reinforce and support that thing
this can be risky, because if the jews become aware of this, they may try to fake their fears as a way to control what is going to get reinforced or just to divert the efforts towards something useless and harmless to the jews
But then again, seeing what the jews are really scared about is part of the requirement for this tactic to work at all, same goes with recognizing what they truly fear from what they are faking to be worried about.
