Source for hacked email is official Iranian state media Tasnim.
Given that most right-wing Americans are extremely pro-Israel, and the military recruits largely from the right, there's a high chance that "anti-Semitism" in this context means "not wanting to die in the Middle East for some other country's interests."
"Anti-Semitism" in American political rhetoric tends to be just a code word for "not supporting the most militant wing of the Zionists."
