It was never meant to, as it would interfere with Israel's use of Starvation as a cheap Final Solution for Gaza.
It was only ever meant to generate the right kind of images on TV in order to sway enough Progressives to keep voting for Biden so that he wins the upcoming election.
The whole thing is pretty much like a slum landlord loudly "giving money to Charity" whilst squeezing large numbers of poor tenants who have no other options with expensive rents and bad conditions: a symbolic "positive" action propagandized very loudly while far vaster negative actions are kept as much as possible quiet, so that for outside observers - who judge the scope of those actions by what they see rather than what is actually happenning - the total looks like positive and they conclude this is a good person.
Of course, as per the track record of the American and Israeli propaganda so far, the failure of something which was always meant to fail is, just like every single bad action by Israel without exception, blamed on Hamas.
