Israel similarly violated the ceasefire prior to 2008, and had unlawfully kidnapped and imprisoned hundreds of Palestinians. Furthermore, Israel's attack on Gaza was not an act of last resort. Israel could and should have tried to negotiate a truce with Hamas based on the following principle: an end to the Israeli siege on Gaza in exchange for an end to Hamas-led rocket attacks on Israel. This is the deal Hamas offered Israel before Operation Cast Lead was launched. Israel should have accepted Hamas’s offer and assessed whether Hamas’s intention to be bound by its terms was genuine before launching a military attack.(6) If an action isn't truly an act of last resort, it cannot be legitimately termed 'self-defense', and so is not justified. Hamas were prepared to enter into negotiations with Israel and it was prepared to discuss the more intricate details of the deal it had proposed. Its attempts to avoid conflict were committed and consistent enough to suggest that Gaza’s leaders were not engaged in diplomatic posturing or sabre rattling. Israel targeted more than just military targets, including UN warehouses holding medical and food supplies, UN schools, and hospitals. Its imprecise tactics and refusal to allow access of humanitarian workers show that it was not merely self-defense.
