oh, no doubt about it!
but that is just due to strong lobbying, and diplomatic bias. But i dont think Egypt is reliant on israel for survival.....even though diplomatic TIES with israel are to its convenience. It gives some "assurance" to the U.S. that they wont pose threat to israel. We could also talk about how it puts pressure on Egypt government NOT to allow the opening of Rafah border, which would provide some relief to Gazans under blockade.
you know how it is with the Americans, when it comes to defence related acquisitions. Unless they REALLY need you ---there is always a catch; always strings attached, etc.
and it still appears that israeli lobby groups like AIPAC are pretty powerful, and can block high tech goods to countries within its neighbourhood and even beyond.
In fact, i'm surprised that Lockheed Martin was allowed to sell Egypt the LANTIRN/Sniper targetting pods (it was either one, or the other, or both).
