was conceived in three major urban centers – Rafah – Khan Yunis – Gaza City – around which security zones were built . The strip had three lines of defense – 1. the central zone of the city (defended by elite troops – commanders); 2. City entrance area – Defended by light brigades disposed in the eastern area in the form of semicircle; 3. the first line of defense (in the form of a security border) along the 64 km of the strip . In fact, the strategy designed by the leaders of the movement is very interesting to avoid a possible encirclement. Underneath each city, they dug long miles of tunnels through which they went outside the city, having the ability to surprise the enemy by attacking back attacks .
As for defensive weapons, Hamas uses the following defensive devices :

‘ Mine ‘ Anti-tank, Anti-personnel
‘ IEDs ‘ improvised explosive devices ‘ different types
‘ IEDs cu EFPs ‘ explosively formed projectiles ‘ Shawaz

In this context, the bilateral relations between the two sides were marked by:
1. The initiation of superficial bargaining efforts, which have proved to be impossible to respect. The main aspect that permanently amplifies these military confrontations is the existence of an impressive military arsenal that can be used anytime.

3. One main cause of the failure of the agreements signed between the two parties is that the penalties stipulated for the reopening of the armed conflict were not respected and the international com
