There is no absolute truth. Just like there is no absolute good or evil. Hero to one is always a villain to another. If Israel will not protect its citizens, no one else will. If they get hurt, the responsibility will be of the government of Israel for failing to protect the people.
The Arabs in Gazza, however, should place the blame with its government for refusing to wise up and protect the life of the people. All it would take is to rethink its stated goals of death and destruction and replace them with life, love, and prosperity.
That simple.
