The military operations were necessary for long term peace:  As Michael Oren and Yossi Klein Haleviargue explain, “the Israeli public will not make territorial concessions on the West Bank or the Golan Heights if Gaza is allowed to become a neighboring terrorist state that can launch attacks with impunity. Israel had already had a bad enough experience letting that happen with Hezbollah in Southern Lebanon.”(1) Without the assurance that they will be allowed to protect their homes and families following withdrawal, Israelis will rightly perceive a two-state solution as an existential threat. They will continue to share the left-wing vision of coexistence with a peaceful Palestinian neighbor in theory, but in reality will heed the right's warnings of Jewish powerlessness.(4)  Meanwhile, the stronger Hamas becomes, the more resistance moderate Palestinian President Mahmoud Abbas will face to making any concessions to Israel.(1) Therefore damaging Hamas, via Operation Cast Lead, actually aided the peace process in the long run, and was necessary in order to make an eventual two-state peace solution possible. The Israeli attacks may also eventually help force Hamas to accept a more durable ceasefire. Unlike the botched invasion of Lebanon in 2006, when Israel set itself the unattainable goal of eliminating the military capability of Hezbollah, during Operation Cast Lead it was made clear that the objective was not to wipe out Hamas, but instead to force the radical group to accept a durable cease-fire on Israel's terms.(8) This was necessary as prior to Operation Cast Lead Hamas showed no interest in peace, opting instead to pursue its political objectives through the use of terrorism. When Hamas came to power in Gaza in January 2006, it failed to control the rocket fire from the variety of miltary brigades, including its own al-Qassam brigade, into Israel and failed to establish internal stability. The widespread violence between Fatah and Hamas, which ended in June 2007, when Hamas took control of Gaza and ousted leaders of President Mahmoud Abbas's Fatah movement, made Israel more wary of the security threat an unstable Gaza could pose.(9)  In Israel's view, Hamas' behavior and its reliance on terror tactics will never change if it thinks it can attack with impunity, and so the Israeli military operations were necessary and justified in the name of restoring Israel's deterrent and weakening Hamas, both of which make long term peace more likely.
