There are plenty of committed antisemites out there who really believe that the Jews and Israel control the world and cause all its problems. These crackpots have always existed. Way back in the 19th century, August Bebel characterized antisemitism as "the socialism of fools." It is still that. Many socialist fools who know nothing about the Mideast have become virulent anti-Israel bigots, with some crossing the line to overt and unapologetic antisemitism.
