Israel has been under the most profound siege since the fall of 2000; some would say, since the day after it won the 1967 war of self-defense; others would insist that the siege began the moment the sovereign Jewish state came into being in 1948.
They are all right.
Hamas rockets have been launched against Israel for years now — only the world refused to see or hear them or to understand what this meant in human and civilian terms. Jewish children, (adults too), have been traumatized by the siren which tells their parents and teachers that they have 30 seconds to reach a shelter; they have been traumatized by the chronic and unexpected sound of explosions, the need for gas masks (!), the need for bomb shelters.
