"If you want to strengthen this city, it should be filled – not emptied," he added.
The town's residents, many of whom have left the city, have complained about the government's "helplessness," particularly in terms of building fortifications.
Internal Security Minister Avi Dichter, who moved his office to Sderot, told the cabinet meeting on Sunday morning that the IDF's operation in Gaza was not enough to prevent the rocket fire.
"It doesn't make sense that the military activity focuses on 'targeted killings' and Sderot and Gaza vicinity residents are paying the price," he said. "Without creating significant deterrence, we will continue to be hit by Qassams. Life is peaceful in Beit Hanoun and Beit Lahiya – 3 kilometers away from Sderot and Yad Mordechai."
Lebanon War's lessons
State Comptroller Micha Lindenstrauss also visited Sderot on Sunday for a meeting of the Knesset's State Control Committee. Addressing his report on the fortifications of buildings in the city, he said that "those who read the report saw before their eyes the failures we found here, which cannot be swept under the carpet."
The committee's chairman, MK Zevulun Orlev (National Religious Party-National Union) compared the situation to the Second Lebanon War, saying that "although the State of Israel has experience with suffering, it appears that not much has been learned."
Deputy Defense Minister Ephraim Sneh told the cabinet meeting that in 2006 the Defense Ministry had decided to invest NIS 40 million (about $9.88 million) in the examination and development of an Israeli defense system which would provide an answer to rocket attacks both in Sderot and the Gaza vicinity and across Israel.
"There is no contradiction between an effective and passive fortification. The system is part of a larger project which will meet the needs of the entire State of Israel," he added.
As he left the meeting, Sneh said that the Israeli operation in the northern Gaza Strip "did not start in the morning and will not stop this evening. This is an ongoing operation, and its strength and effectiveness lie in our persistence. A different target is attacked every few hours, whether it’s a machined manned or being used by Hamas or a Qassam launcher being destroyed."
Addressing the possibility that the IDF would enter the Strip with ground forces, Sneh said that "entering is not an escalation, but another way to reach our goal. At the moment our entry is very limited and we are focusing on an aerial war which has killed 160 Hamas members."
