For many years, Israel has been proving its utter helplessness in the face of the widespread, incessant and significant violations of the peace agreement between Israel and Egypt, by introducing huge military forces (more than a division) into the Sinai Peninsula.
The Egyptian army, in an attempt to justify its steps, claims that these are not violations but rather Israeli agreement to Egyptian requests to send forces to Sinai in order to fight ISIS forces operating throughout Sinai.
Israel, for its part, does not respond to these violations, which encourages the Egyptian army to further increase the flow of forces into Sinai.
It has been known for many years that the Egyptians have prepared extensive fortifications to quickly absorb more than 10 divisions that will be unexpectedly sent into Sinai if the Egyptians decide to act against Israel or Even just to threaten it.
