nah he's not opposed to it at all
The suspension of weapons to Israel is not a full-on suspension of weapons shipments, but rather a conditional and temporary pause on one specific weapon (large bombs)--Israel is still getting most of the military aid and intelligence support the US provides it, and Israel was already well-supplied anyway.
The US and Israel overestimated how much Oct 7 was going to let them get away with, so all of the "opposition" Biden has had to anything Israel has been doing since Oct 7 has entirely been PR stunts in order to try to preserve America's self-proclaimed image as the ultimate good guy of the world, as well as try to retain voters in an election year, since it's obvious that Gaza is giving people yet another reason not to vote for him this November. It's all empty words and meaningless gestures and stuff that is far too little, far too late. If the US really cared about the obvious genocide Israel is committing in Gaza, it would be doing a lot more about it, and it does have the power to do so, yet it chooses not to.
Something to keep in mind is that Israel has for pretty much its whole life enjoyed very strong bipartisan support from the US government, and that's not changed one bit. And as (the blue flavor of) American establishment incarnate, Biden was never going to deviate from that. There was never any reason to believe that the U.S., which has been happily supporting Israel's long campaign of discrimination and murder of Palestinians for decades, when the U.S.'s entire history is just one unending chain of oppression, genocide, and imperialism, was ever going to have a moment where Israel went too far for it and have enough of a conscience to try and stop it. Netanyahu knows that, no matter what Israel does, the US will always support it, so it's easy for him to act tough and be all like "Israel will do this alone if we have to!".
The media just likes to overstate Biden's words and gestures (and make it seem that the Democrats are divided on the matter when really it's only a handful of voices that have any serious opposition to the genocide in Gaza) for political reasons--either to try to prop up the idea that, no, Biden/the US isn't condoning genocide as well as basically prepare Netanyahu as a scapegoat if necessary (despite the fact that the problem stems from far more than just Netanyahu), or to portray him as weak and giving into the "radical far left" and abandoning such an important ally (an important ally for American imperialism anyway).
And Biden's phone call to Netanyahu to warn him was all for nothing,or was nothing? Plus, do you have proof that that his opposition is PR, all aside from this October 7 thing? What happened in October 7 only does so much, and does not cover or deal with everything Biden thinks on something like this. To me, that is like saying a news source is untrustworthy and biased even though they tell the truth.
Plus, if Biden supports Israel's actions, which I doubt he does, and supports Israel's genocide in Gaza. how do you explain this?
Once the pier is completed, it will initially facilitate the delivery of an estimated 90 truckloads of international aid into Gaza and scale to up to 150 truckloads once fully operational.

He has been trying to make an aid to deliver aid to people in Gaza, which would probably not happen if Biden was supporting Israel's actions. Also, just because Israel enjoys strong support from the USA does not mean the US can oppose some things they do. Plus, I think you are generalizing the media and what they say about Biden here. Not all news media tell lies, you know. In fact, I think you are just being too untrustworthy of media to the point that you think all of the media can't be trusted. Not all news media is like, say, Fox News, which has a history of being a not-so-good news source.
Plus, just because Israel may be an important ally does not mean the US will not condone what they do and abandon them at the same time. You act like there is no in-between here in regards to the US and Biden supporting Israel or not. It seems you are underestimating the US and Biden here, like you are saying they can either just support Israel or not. It does not have to work that way.
I am not saying Biden is the best here or that he has no flaws, but I do not think his actions are really being understood here, and I think his actions are being dismissed for the wrong reasons. Besides, the unending chain of "oppression, genocide and imperialism" thing, even if that were fully true, you do not seem to realize that there have been good events in the USA, too, like civil rights movements and other changes and good things. I think you are just focusing on the bad things of the USA, plus, the USA is not the only one guilty of those things, too.
