Biden wasn’t close to perfect. He wasn’t hard enough on Netanyahu, opting to express frustrations with him privately rather than through policy, because being pro-Israel is a popular view in the US.

Biden circumvented Congress and violated standing law to fund a genocide. The bare minimum was not aiding Israel in any way, and he did not even entertain that.

Setting aside that Israel's ongoing genocide isn't actually popular, say it was for the sake of argument. That still doesn't mean you support it. You may have to actually do your job as a politician and shape public opinion on an important matter, or even do the right thing despite it potentially harming your career. Again, bare minimum stuff.
