"What Cast lead did was force Eygpt to first admit there was smuggling and now they are building a wall to stop it completely..." Retrofitting objectives in order to fit the present picture is not at all convincing. This was never an aim of the Israelis in embarking on Cast Lead. Hint; Egypt has been co operating with Israel on the siege since it began. It even requested more troops to find the tunnels, but Israel was reluctant to breach the Sinai peace treaty limitations. Israel and Egypt simply did not consider this option seriously until now. In any case do you really expect the wall to stop tunneling? If it does not do so completely is one to assume another decade or so of siege and if so at what point will the diplomatic fallout of such a strategy finally render it unacceptable. Before or after al Queda affiliates and hardliners prosper at Hamas and Fatahs expense? "Go and ask the residents of sderot if cast lead has reduced the Rockets comming in.." Again, as pointed out to you, the rockets have been reduced but not by nearly as much as during the ceasefire. So it can not legitimately be regarded as a primary goal.[since a ceasefire is much cheaper both economically and diplomatically than a Cast Lead]. You totally ignored the diplomatic fallout in your posts, even after prompting. In reality Israel greatly underestimated this and this MUST be considered in any rational assessment.
