If you're in Hazony's nationalist camp, you support Trump. Hazony himself seems to think there are no real problems between Jews and non-Jews within the nationalist (Trump) camp. "Liberal" Republicans and liberals (Hazony blurs some lines here) are attacking nationalists as
liberals, who are therefore not interested in building bridges with their political opponents. (Leave aside whether Mark Levin, Ted Cruz and Ben Shapiro have, in fact, attacked "nationalists," rather than the "alt-right.") Jews outside of the nationalist camp (most of them,
obviously) also have no interest in building bridges with nationalists. Withing the nationalist camp there seems to be no need to build bridges, then, unless Jews in the nationalist (Trump) camp have been accusing other nationalists of antisemitism. But then it's a question of
whether the accusations are accurate--presumably, if they are, then the person accused is "alt-right" rather than "nationalist." If there's a real question here it's what counts as "antisemitism," if that's going to be the issue (rather than, say, subverting Trump, which the
"alt-right" does systemically). But, again, no bridges need to be built within the nationalist camp--all those supporting Trump are working together (otherwise they're not supporting Trump). So, what is Hazony getting at? I'm guessing this comes down to the Carlson-Vance
connection, and Hazony wants to join those attacking anyone highlighting this connection and tracing its implications for Vance's statements and acts. A lot has been staked on Vance, so there's a lot to lose.
