 The U.S. military-built pier to carry humanitarian aid to Gaza will be dismantled and brought home, ending a mission that has been fraught with repeated weather and security problems that limited how much food and other supplies could get to starving Palestinians. Critics called it a $230 million boondoggle that failed to bring the level of aid needed. The U.S. military, however, has maintained it served as the best hope as aid only trickled in during a critical time of near famine in Gaza and that it got close to 20 million pounds of desperately needed supplies to Palestinians.
