Spoiler: she won't. Werhmacht Walz already expressed support for "Greater Israel," ie accelerated and expanded settler-colonialism and genocide.

Harris supports Israel because the US Empire needs it. It serves as a rabid dog for the US to terrorize the Middle East, securing the Petro-Dollar by which the US maintains monopoly over global Financial Capital, and Imperialism in the Global South.

She will not change, it isn't a moral issue but an economic one.

It's far more preferable to the ruling class for the Republicans to win one.

She's not a progressive tho. Why would you expect her to gave progressive policies?

What the dems care about is that their donors keep funding them. If they lose the election, then it doesn't actually matter because they'll still get the same money they're getting now. However, if they win the election and piss off the donors then they lose money.
