I think you're wrong about this because these things are connected. The path to the white house was a Berniecrat campaign. They had to push an anti-corporate narrative really hard and rely on grassroots donations to get way more people involved, naturally boosting turnout. Part of the anti-corporate (not necessarily even socdem, but bonus points if it was) strategy absolutely would've been standing up to the MIC. There was a way to victory that confirmed people's doubts about the economy with a substantial policy platform that wasn't pandering to petit bourgeois pigs.
Think about the alternate reality where Kamala's strategy was to run a far more progressive campaign. She would've depended on orgs like DSA to drive the message home that she was trying to appeal to those voters; that doesn't necessarily mean she would have had to drop Zionism from the campaign since the DSA is spineless and there is no organized left in the US that could make a demand like that, but it certainly makes it a lot more likely that she would've considered the pro-Palestine political block a more expedient group to capture than Zionist voters.
