This source doesn't seem terribly credible, and I don't have the capability of evaluating the Israeli website for its credibility either. If this gets picked up by a major news organization, as credible it would put a very interesting spin on the global politics.

Not sure how they're going to get Egypt to agree to absorb 2 million refugees. Egypt has been explicit about not wanting more Muslim brotherhood supporters in their borders. Egyptian officials have even made statements to the effect of, if the West cares so much, they should accept the refugees.

From a military perspective, Egypt would be insane to accept the refugees, because now Israel would have a military target to attack next time the displaced population lashed out. They would start attacking Egyptian military installations, on the theory that you need to be controlling your people. And I'm sure Egypt wants to keep its military equipment intact
