Under the same logic, over 1 million residents of Gaza have been under occupation since 1967, facing limited rights of movement, regular air raids, military checkpoints, random searches and seizures, random arrests, the destruction of sanitation facilities, homes, schools, roads, shops, markets, and health facilities, and therefore Hamas has the right act in its own self-defense by whatever means it sees fit. If Palestinians do not have an army to call to its defense, how can the entire population be punished for the actions of non-state military groups?  Israel’s right to take positive steps of some kind in the interests of its own safety does not mean it has the right to do anything it wishes in order to protect itself. It is also evident that Israel violated international law and committed war crimes, was was reported in the Goldstone Report.  Between the time when the shelling from Gaza started in 2001 and Operation Cast Lead, 20 Israeli civilians were killed by rockets or mortars, according to estimates by Israeli human rights groups. That doesn’t justify an all-out ground invasion that killed more than 1,400 people.(10) As Javier Solana, chief of foreign policy for the European Union, said in late December 2008, "the current Israeli strikes are inflicting an unacceptable toll on Palestinian civilians."(14)  It is a widely accepted principle of international law that actions taken pursuant to a state’s right to defend itself must be proportionate to the danger that the state faces. While the 20 deaths that resulted from the actions of Hamas and its associates were tragic, the nature of these attacks did not justify a full scale military invasion of the Gaza strip, or the mass destruction of infrastructure essential to life in the strip.
