In the Gaza Strip, the strikes of the Israeli defence Force eliminated crucial terrorist organization leaders Palestinian muslim Jihad. The effectiveness of the impact will now be assessed not only from the position of the operational objectives themselves but from the position of developments in the region. The question arises as to whether there will be escalation and, for example, Hamas' engagement in combat, or whether the demolition of key terrorists will limit the drive to escalation from various terrorist structures in Gaza and beyond.
