I think announcement will simply bring into the foreground, into the light, the massive underlying anti-Semitism–the racism, to be clear, the real, old school fertile ground from which mass murders and judicial injustice have long proceeded–which causes people to hate Israel so much.
There is no just reason to hate Trump the way he is hated. He has simply brought the underlying hate–which sought and often found plausible covers behind which to hide–into the light.
Likewise, what drives Israel hatred is not love for the so-called “Palestinians”–who in reality are refugees, the children of refugees, and the grandchildren of refugees, from what I have taken to calling the 1948 War of Israeli Survival, who all should have been permanently resettled long, long ago–but rather hatred of Jews.
Real racism still exists in this world. It is clearly and pervasively tolerated by those most eager to accuse everyone but themselves of this particular crime, and quite frequently practiced outright. If you hate white people, you are a racist. If you hate Jews–even if you are a Jew–then you are a racist.
What I see is that so much of this is simply cover for underlying, psychodynamically driven rage, which is then easily harnessed–and indeed amplified and fed–by political cynics and opportunists, for their own greedy, power mongering, selfish agendas.
