How would you deliver aid in a way that was guaranteed not to kill anyone? Trucks? Nope, those kill people every day. Push carts? Nope, too slow and people would die of exhaustion. Boats? That takes a dock and we're building one. (And people can die that way too.)

I personally don't think Biden has the ability to force Israel to do anything unless he does it through military force, which I don't support. Russia or China would quickly fill the vacuum if the US just pulled out. Ramping up pressure over time maximizes the US's influence over Israel. I think Biden should have ramped it up a lot faster, but it is the most effective strategy.
