Hamas never enters into truces with an eye to peace. It enters into truces with an eye to getting its troops rested and rearmed before the next offensive. Israel, equipped with knowledge of both core Islamic doctrine (hudna) and Hamas’ own past behavior, nevertheless keeps giving its opponent a breather, rather than keeping the pressure on when Hamas is on the ropes.
When I was growing up in the 1970s, common currency in the Jewish community was the joke about how much smarter Jews were than their Arab opponents. The one I remember best from the 1973 Yom Kippur War (although it’s certainly not the best joke) went this way:
Shocked by their losses, the Arabs regrouped and began studying their Israeli enemy. They realized that one out of every three Israeli soldiers was named David. They therefore came up with a new strategy. When they were within shouting distance of the Israelis, the Arab soldiers would holler out “Hey, David,” confident that the David’s would rise up, ready to be shot down by snipers. It didn’t work quite as planned. When the Arabs yelled out “Hey, David,” the Israelis would holler back, “Is that you, Mohammed?” Half the Arab soldiers would then rise up and get shot down by snipers.
Bad joke, but you get the point. These jokes have no currency now. Israel has been strategically out-thought at every turn. All she has left is brute force.
