Hamas continues to smuggle weapons into Gaza - and uses Israel. Israel's armory includes missiles from the Vietnam era that have not been used by the United States and other military powers for a long time.
Each new round of fighting leaves more rubble from which Hamas fighters collect pipes, concrete and other valuable material for new bombs. Food, consumer goods, cars and fuel also enter the Gaza Strip through the tunnels. Israel suspects that a number of terrorists from the Islamist organization are hiding in the underground passages and are also holding hostages from Israel.
