This is exactly what the Nazis did, they tried to justify the mass industrial slaughter of the whole by claiming to be attacked unprovoked by a subset of uprisers and making antisemetic justifications while crying about bankers. Gas and Cry is what the Nazis did. Main difference is that now flying demons vaporize children into a thin instead with 2000lb American bombs.
Just as Nazis don't get to reductively define nazism (as simply the right to an Ubermensch Lebensraum) after 15 years of atrocities and 1 holocaust, zionists do not get to reductively define zionism (as simply the the right to a Jubermensch Lebensraum) [I'm impressed that you've reduced it even more as merely "the right for Jews to exist", nice try] after 76 years of atrocities and 1 holocaust. Both are defined by their victims!
All these narrative traps do not work anymore. There is no justification for committing a holocaust. Not now. Not then. Not ever. No matter claims as to who controls what, no matter why rose up against whom, no matter whose religion says what.
Truly embarrassing for humanity that that has to be said.
And speaking of a ratio to 300:1, that is the death ratio that Israel has exacted upon the population of Gaza per Lancet. Surprisingly that ratio did not apply to the Germans, as per demonic Israeli calculator there are currently 1.8bn (300 * 6m) too many Germans alive today. Quite forgiving to the Germans for some reason (see: Otto Skorzeny).
