In order to understand the nature of the strategic surprise inflicted by Hamas on Israel on October 7, it is essential to understand its jihadist orientation, which was formulated on the movement’s founding and has never changed. While Israel employs a Western military concept that avoids war and sanctifies the value of life, the jihadist concept aspires to self-sacrifice, death, and a cosmic religious struggle against “Jewish infidels.” Hamas has no concern whatsoever for the welfare of the local Gazan population, which means it does not have the Achilles’ heel of the Israeli side: the commitment to uphold the sanctity of life for both its citizens and its soldiers. Israel continues to operate using a Western democratic approach in the face of an eternal jihad. It will have no choice but to fight the jihadist mindset without any containment or restraint.
