'Civilized People Do Not Starve Children to Death': Sanders Rips US-Backed Israel's 68-Day Gaza Aid Blockade | Common Dreams
www.commondreams.orgU.S. Sen. Bernie Sanders calls out the humanitarian crisis in Gaza as Israel blocks aid—and the United States' complicity.

At this stage Israel controls the Rafah crossing, so Egypt doesn’t have a way to send stuff in unless they try to force the issue with military involvement.
And obviously they’re dependent on the US for military aid, so if they tried they’d get cut off immediately.
