Wow. How out of touch with reality are you? Israel is fully supported by the entire US government, including many Democrats and almost all Republicans. Biden couldn’t (realistically) cut off support even if he wanted to. Israel is far too important to US interests in the region.
Israel is completely responsible for their own actions. The US isn’t telling them to commit genocide. The International community isn’t doing anything to stop them. All the finger wagging and hopes & prayers are just virtue signaling. The sad fact is no one in power really cares about the Palestinians.
Putting all the blame on Biden/Harris is some Russian shill-level propaganda. That, or you know nothing about international politics.
