I can’t figure it out either. My standard explanation is that their liberalism trumps their Judaism.
It’s mostly the secular Jews who sell out Israel for leftist policies. The religious ones are mostly Republicans.
Jewish people are.exploited by all sides of organizations with influence (they aren't alone really) it has been happening in Canada for decades. I simplify this when I say that the only true friends they really have are those spiritually and morally supportive. We want peace among all in the region and will call out evil.
Police (certainly in Canada), some even on this forum; reflexively support Israel because they believe they are "tough on crime". We even have some in Canada going back 30+ years who profit of off "hate" that they themselves manufacture antisemitism I know, they tried it with me with a full court press for years whioe in high school, even in the workplace! This is because they wanted any excuse to "get me" since I wasn't a criminal (they were). I might even write a book on the subject...
Politicians see votes or a way to sell weapons for their donors. Those who genuinely care are surpassed by those looking purely for their own interests. It's like many climate change or race-baiting "leaders". They don't
really care about the environment or abuses unless there is profit to be made. Sadly this is true of TOO MANY issue we should courageously confront, even if we doknt benefit personally.
Evangelicals and most Christians see the founding of our religion and we connect with Judaism. This doesn't mean Muslims don't deserve (and many want) peace too, I support all peace loving citizens. It is just that the Old Testament and Abrahams history is where it all started.
For me it is multi-pronged, from common beliefs to spiritual alignment, on top of the recogniition that Israel is surrounded by those who don't wish them there. As an underdog and bsttler my own life, it makes sense to defend those who have had the courae to defend their nation. None if us get votes or profit from war there, we want peace and despise terrorists who targe civilians.
