It's framed as "Jews have allegiance to the Jewish nation which compromises, and is stronger than their allegiance to Canada". This is just basic anti-Semitism.
That's not the framing. It just highlighted the 3 to 1 disparity and came to the conclusion that mainstream Jewish institutions effectively indoctrinate these Jews into joining the Israeli military.
“The vast majority of Canadian Jews do not join the Israeli military. However, mainstream Jewish institutions in the country — synagogues, schools, camps, etc. — generally valorize the Israeli military, pass this framing of it on to youth and offer opportunities for them to immigrate to Israel, which almost always entails becoming a soldier. Those who join the military are not on the fringes of their community, but rather have taken the direction by mainstream institutions to serve Israel to its furthest extent.”
