It's a twist in scripture to force-fit their idea of anti-christ.
Anti-christ will be muslim (the whole beheading thing). He'll come from a muslim country of the Selucid portion of the Old Greek Empire.
NO ONE in the west can force muslims to give up the temple mount so as to share it with the rebuilt temple, except a muslim. Definitely the Jews would not listen to the pope.
NO ONE in the West is the anti-christ. End of biblical story.
