TEL AVIV, Israel (AP) -- The savage fighting between Israel and Hamas is escalating in Gaza, cease-fire efforts take on elements of farce, and bravado rules the public discourse. But even through the fog of war, a few endgame scenarios can nonetheless be glimpsed. For the moment, the deadlock is well-entrenched: As long as the crippling blockade of Gaza remains in place, Hamas says it will continue firing rockets at Israel - terrifying but mostly ineffectual, thanks to the "Iron Dome" defense system.
