That is the major reason why I am not accepting Keith's assertions that Israel is trucking in sufficient for Gaza to export food.
Israel applies no restriction on food.
They can import through Israel as much as they want.

The export of tons of date bars by a UN food agency was just mentioned as an indication of the plentiful food.
Gaza exports hundreds of tons of agricultural produce.
I listed some.

Israel does not maintain or control the crossing between Gaza and Egypt.
How could it.
Yes they built it when they were still in Gaza, but the Egyptian side was always manned and controlled by Egyptians as anyone but you would think obvious.
