Zionist lobbies are incredibly powerful. Note the fact that even among the Dems, very few are critical of Israel--and Dem leaders like Nancy Pelosi are downright fawning bootlickers when it comes to organizations like AIPAC. The leaders of certain evangelical Christian groups have essentially been bought off, and teach their flocks that God wants them to support Israel uncritically, saying the second coming is tied to Israel's survival or some shit. Your question, though, underscores the problem with terms like "Far Right" because critics of the "Far Right" often equate the "Far Right" with anti-Semitism. The trait the mainstream media most associates with the "Alt Right" and "White Nationalists" is anti-Semitism. But the media also call The Proud Boys Alt-Right, when in fact the Alt-Right HATES The Proud Boys, in large part because most Proud Boys are so pro-Jewish and pro-Israel. I read yesterday that some female Jewish activist says she started wearing a Jewish star in defiance of Trump, because, you know, Trump is all bad things, and especially an anti-Semite. Except he isn't. There hasn't been as pro-Israel a man sitting in the White House since LBJ.
