Biden is pro-Israel but also pro-Palestinians.

Biden’s Increasingly Contradictory Israel Policy: A former State Department official explains the Administration’s sharpening public critique of Israel’s war and simultaneous refusal to “impose a single cost or consequence.”

Right now it seems like the Biden Administration is trying to pressure Israel not to launch a military assault on Rafah and to allow in more humanitarian aid. At the same time, it has shown an unwillingness to take strong steps to punish Israel or to restrict the flow of aid or weapons to Israel if the Israelis disregard that pressure. How do you understand the strategy now?

I’d call the Biden Administration’s approach “passive-aggressive.” They are angry at Netanyahu, and were even before this. He’s presiding over the most extreme government in the history of the state of Israel. That government and the preceding dozen years of Netanyahu’s tenure are undermining the two fundamental drivers of the U.S.-Israeli relationship, which are shared values and common interests. So, it’s passive-aggressive in the sense that, six months into the war, the Administration has still been unwilling—unable—to impose a single cost or consequence that you and I, as normal human beings, would describe as real pressure.

Unable or unwilling?

Both, but I’ll get to that in a second. There were three levers the Administration could’ve pulled. They’re still available. No. 1 is to end U.S. military assistance. There’s no indication the Administration’s anywhere close to that. It just approved a shipment of two-thousand-pound bombs, and twenty F-35s. No. 2, change the U.S. voting posture at the U.N., either by introducing its own Security Council resolution, or by voting for someone else’s, that is very critical of Israel. It has not done that. No. 3, abandon the whole notion of negotiating the hostage release and simply join the chorus of those in the international community who basically say, “You need to pressure Israel to cease this military campaign.”

And I think it has not done these things

Biden is pro-Getting Relected. And he recognizes that his party is increasingly pro-Palestinian. However, his current policy appears to be a CYA strategy, intended to create the illusion of neutrality while negotiating a path that allows Israel to continue its extermination of Arab people across the region.

As this exterminationist Israeli agenda becomes more undeniable, the job of appearing neutral grows more difficult. And Biden's decision to (tacitly) back Israel at all costs means risking friendly relations with Turkyie, Jordan, Saudi Arabia, and Egypt. However, he's staying the course, precisely because he's banking on a mass expulsion and genocide of Palestinians today will strengthen Israel's regional position in the future.

If someone gives a sandwich to me and a gun to a person actively trying to murder me, they are not "pro-me"

An alternative explanation is that what he says and what he de facto does are two entirelly different things.

Being pro-Palestinian would require demanding Israel stop murdering them.

Look at what is done, not what is said.

The Nazis also proclaimed to be helping the Jews as they were putting them into Ghettos and then industrially murdering them in the Concentration Camps.
