It's not that Jewish ideology can't be subverted for various ends or as rationalization for particular behaviors. Of course it can. But it really does not lend itself well to fratricidal warfare. The cultural conditioning factor is extremely strong. Heck, we have a whole fast day after Rosh Hashanna dedicated to precisely the idea that Jews don't kill Jews. Even the more heroic acts of warrior zealotry, such as those around the destruction of the 2nd Temple, have a decidedly mixed reaction in Jewish tradition.
By contrast, self-sacrifice is practically hardwired into the OS. Note we will mark the New Year with the reading of the Sacrifice of Isaac.
Not that it couldn't happen, and things can always spin out of control. But it takes a heck of a lot to move from obnoxious behavior to actual armed, organized violence.
