Biden is so outraged that just in the last 4 days or so he’s promised the sale/transfer of tens billions of dollars worth of F-35s, F-15s, and huge bombs for Israel. His talk of grief and anger is cheap political theater to save his presidential campaign and anyone who actually believes him is wilfully blinding themselves. His words only changed when people started voting uncommitted, and his actions never did. What he actually does, which is the only thing that counts, is force US money to enable nation-level war crimes whether or not the citizens want it.
