Americans in huge majorities support the Jews’ Gaza genocide.
Biden’s position on Israel has jacked up his popularity rating a lot, maybe by 10 points. These guys read polls. As long as solid majorities of Americans support Israel’s genocidal policies, it’s political suicide to oppose them.
It’s the American people you have to work on, not Joe Biden or Congress or those elusive Jews behind the screen in the US, pulling the strings on the puppets. None of these people would be able to do what they do without the extreme support of the governed.
