The U.S. military-built pier to carry humanitarian aid to Gaza will be dismantled and brought home, ending a mission fraught with weather and security problems. As the military steps away from the sea route, questions remain about Israel's plan to use the port of Ashdod as a substitute. There are also concerns about whether aid groups will have enough viable land crossings to get supplies into the territory besieged by the Israel-Hamas war. Critics call the pier a $230 million boondoggle. The military argues it got close to 20 million pounds of supplies to Gaza. The steel pier segments were shipped to the region from an Army base in Virginia.
