Biden isn’t “committing genocide” and saying he is amounts to simple propaganda.
The conservatives want to take aid away from Ukraine to deliver it to Israel. If Trump wins, far more weapons will be going to Israel than they are now. Repeating propaganda like this is not helpful for the Palestinian people.
Lastly, Israel is an important ally from a strategic perspective. Not only are they our closest ally in the Middle East, but they have a number of important resources like intel semiconductor facilities. Cutting ties with Israel would be bad for America, and the role of the US government is to put America first. It’s more complex than simply supporting one side or the other and Biden is attempting to balance aid for Palestine with preserving our relationship with Israel. That’s exactly what a good president should be doing.
