text:  A multi-million dollar pier the U.S. military constructed in Gaza may soon be no more. It's been removed before because of bad weather, but this time it may not be put back into place on a beach in Gaza. That's because so much aid for Palestinians remains in the storage facilities there, and that's due to security. Humanitarian groups say their trucks have been looted and their drivers threatened, and many have refused to work. CBS's Cami McCormick reporting.
