On Wednesday the last of Israel's troops left the Gaza Strip.
The cease-fire was however frayed when its navy opened fire toward beaches in northern Gaza, and smugglers' tunnels that were targeted in the 23-day campaign against Hamas were active again at the Egyptian border.
The next big step is having the fragile cease fire become a truce.
Israeli Foreign Minister Tzipi Livni went to Europe to rally international support for a plan to halt weapons smuggling into Gaza from Egypt.
A key goal of the offensive, aimed at punishing Hamas militants who have been lobbing rockets at Israel for the last eight years, was destroying the hundreds of tunnels along the eight-mile border used to smuggle weapons into Gaza.
According to Israel, 60 percent of the tunnels were destroyed.
However on Wednesday there were signs that they were back in action; making Livni's mission even more urgent.
