I don't disagree with your assessment of Biden, but you're saying this like he's not the better choice of the two. Everything you accuse him of is amplified by entire magnitudes with anyone in the GOP.
And let's be real here, Israel has been a central pillar of US policy for generations. There are one or two high-ranking politicians in the entire government who don't support Israel, but they have zero chance of becoming president. Biden is being chosen not because of one belief or another, it's because of his track record and his experience. He is capable of one of the most important jobs of the office, which is working with the rest of the government, even the people who hate you, to get shit done.
