I think this quote from Harris in the debate sums up the American support for the genocide. You can’t except the former colonial genocidal regime to oppose the new one they propped up.
And so absolutely, I said then, I say now, Israel has a right to defend itself. We would.
Edit: it seems most people think I ment this was a good thing? No, America isn’t inherently good.
This statement shows how America supports the genocide because America would be willing to do similar slaughter if an attack happened to us (look at our post 9/11 actions for an example of the destruction we are willing to cause). It also shows how she not only recognizes but supports this view.
