Right wing politicians are now basically evangelical christians who see Jews as the God's chosen people, so blessing Jews is like being blessed by God to them...No actually, that's not right at all, especially when it comes to antisemitism. As a matter of fact, Americans are very conflicted in how they feel about Israel and the Jewish people. The left are rarely anti-semitic because they strive to be politically correct, but they are anti-Israel because they also desire to be morally just and Israeli behavior is plain inexcusable evil. The right are a very internationally political group and believe in doing anything good or bad (whatever it takes philosophy) for their own conversative views, which is America on top of the world, mainstream white people on top in America. For them, Israeli crimes are applaudable since Israel is politically aligned with the US and so they see Israel as a country that will do anything to further its own interests and by extension, American interests.... but they also hate Jews because they don't identify them as mainstream white America but a little offshoot known for being sneaky and taking economic advantage of others while exercising their own closed off culture. So in summary, both the left and right in America are conflicted; the left likes Jews but hate Israel while the right hates Jews but likes Israel. They cannot straighten out thier tangled thoughts because American ideology is twisted and not wholesome, forcing its citizens to mentally contort in order to align.
And secular right wing are just neocons, many also Jews, who just see profit in wars.
So I don't see how this can add to Israel's problems or antisemitism.
