I don't know... so if Germany loses, there's gonna be antisemitism, and if they win, the result is the same? While I can't scientifically refute this, you should elaborate this.
I thought I did, but I'll recapitulate:
In 1914 Germany was a country that for all its tremendous achievement was unable either to fully dissolve old divisions of society or to face up to new ones. But the outbreak of war created a profound sense- interpreted differently by everyone, of course - of unity and renewal. This included confessional unity and the repression of anti-semitic (anti-Catholic, anti-Protestant) media: the government had no wish to alienate Jews who would join up or buy war-bonds, or Jewish civil organisations that would do organisational and propaganda work.
But as the war dragged on with massive sacrifices of lives and in people's standards of living and victory always out of sight, all sorts of divisions re-appeared: social, political, confessional, economic.
In order to paper over the cracks - and the Jews are such versatile scapegoats: one man blames his poverty on Jewish profiteers, another the strikes on Jewish socialists - the military command from 1916 on ended the restrictions on anti-semitism and indeed tacitly encouraged virulent anti-semitism from right-wing nationalist groups, flooding the press.
In short: German anti-semitism was a manifestation of pressures in society (like anti-semitism in the ex-Russian Empire but with a different society and different pressures); and this was a society which, whatever happened, had been profoundly pressured.
It wasn't just Germany (and Austria); I've mentioned Russia, but in Britain, where the political and social reasons for such explicit anti-semitism were less present, the anti-German rioting had more than a whiff of the same stuff.
But the idea that victory would solve all social problems seems very misconceived to me. It didn't solve the social problems of the victorious Entente. And here's a wee thought experiment: what sort of reception do you reckon I'd get for suggesting that, if Russia had won the war in the east, there would be no anti-semitism among the Slavic peoples of eastern Europe?
