Would it help to think of them as partially being mirrors rather than people? Needing to win elections means they can't push too hard against whatever's popular just because they might not like it.
I would buy that argument if they followed the popular will more often than the "monied will". Most of the western ruling class having financial interests in weapon production through investments in the MIC drives government-level support for Israel's war on Gaza, while Palestine has had popular support for much longer than the current conflict.
