Adam Entous and Nicholas Casey have written in the Wall Street Journal exposing the progress of collaborations behind the scenes between Israel and Egypt to squeeze Hamas:
"A senior Israeli official said the two governments wanted to advance their shared interests and increase pressure on Hamas. But he insisted there was no master plan to squeeze it to the point that 'something would explode.'
"Yet when Mr. Sisi closed nearly all of the tunnels along Egypt's border with Gaza but didn't compensate for the loss of those avenues by allowing the passage above ground of needed supplies, some Israeli officials said they privately began to raise alarm bells about the severity of Cairo's decisions.
"'They actually were suffocating Gaza too much,' one Israeli official said."
