You'll find the Israeli spies on the beach in Sharm al Shiek, not in Sinai
. Not exactly a secret. Israel has every inch of Egypt inspected, they know the locations and functions of every government institutions, they have all military factories pinpointed.
The beduins in Egypt as they are known all over the Middle East can be bought and sold like a hoe. They cause nothing but trouble. Explains why western Iraq, Eastern Syria, and Sinai are largely pro-ISIL. These ISIL scum AKA "Ansar bayt al Maqdis" are not connected to Israel, but they are unknowingly doing them a huge favor.
BTW, the ISIL views Sinai as part of the "Levant", which means get ready for an Iraq style never ending insurgency.
