It’s amazing how big the Jewish opposition to Trump is. But, then again, even the “conservative” Jews can’t be guaranteed not to be pro-amnesty. Look at the Jewish Republican Coalition: pro-gay marriage, pro-amnesty, pro-TPP. Look at Ben Shapiro, calling for ethnic cleansing Palestinians, but calling Trump immoral over wanting to pause Muslim immigration to the country. Even Netenyahu took the time to criticize Trump’s plan, even though Israel is literally not taking a single refugee, and has immigration policies so harsh, Trump would be considered moderate.
I doubt there is a huge flood of Syrian refugees trying to get to Israel, nor do think demanding that a tiny country like Israel with all the geopolitical and religious problems and constraints should take "their fair share" of Muslim refugees is in any way reasonable.
