Who is responsible for this? Well, there is no such thing as a Palestinian attack helicopter, battle tank or anti-aircraft weapon. And looting has without exception occurred between the moment Israeli soldiers enter a building and the moment they leave it. Today they did the Khalil Sakakini Cultural Center, containing the archive not only of its namesake-one of our most famous educators-but also the office of our poet laureate, Mahmoud Darwish. Hardly a coincidence if one recalls the Ministry of Education was ransacked last week.This is the "terrorist infrastructure?" Still sounds like "ethnic cleansing" to me.
