If the Palestinian people were warned before Israel killed two leaders of Hamas, the targets would have moved with the people.
What needs to be done? The Palestinian Authority needs to guide the people in Gaza to a safe haven no matter where that might be. President Abbas was elected to lead and right now his nation of people have the attention of the world. The American wharf is being rebuilt and ships can leave with Palestinians to a place negotiated by President Abbas. He would receive strong support to protect those willing to leave with the right to return.
Gaza is not safe.
