In this Monday, Dec. 19, 2011 photo, seen through a gun slit, trucks with goods destined for Gaza wait to be unloaded on the Israeli side of the Kerem Shalom crossing, between Israel and the Gaza Strip. Each day, dozens of trucks move food, consumer products and industrial materials into the Gaza Strip at this heavily fortified crossing, in an odd arrangement that has turned Israel into a key supplier to a territory governed by its bitter enemy Hamas.
