I don't think fascism and nazis are interchangable 1 to 1, iirc fascism is either a system of government or ideology. while the nazis are a type of fascism. all nazis are fascists but not all fascists are Nazis.
but i can imagine most people stopped learning about history in highschool, so i imagine that when they hear fascist they think nazi then immediately the nazi's extreme disdain for jewish people, so to have a person who is jewish in the company of nazis is enough cause to wave away concern.
In terms on the zionist entity i imagine they wave it away because to have a jewish entity acting in a fascist way is oxymoron from their point of understanding history.
they kindof used that plot in the hbo series "the plot against america" with the rabbi vouching for a vaguely anti semite dude for president
the war in the ukraine is a form of contradiction in capitalism, war is a form of capitalistic competition - right wing extremism grows when there is a low quality of life iirc as people wish to return to a time where everything was perfect and so they need to destroy the out group to get there (the time where everything was perfect doesn't exist).
so if they can have a wonderful life after the war then yeah sure, you can limit it to anti Semitism.
but regardless of who wins the ukraine war, you can imagine that the despair in both nations will be substantial.
