Dear Mr. "A. Sweden", is one different here: Cuba and North Korea are sovereign states with normal trade and limited personal connections with all world. Cuba has, further, massive support of middle- and southamerican countries. Cuba and N. Korea have aeroports, seaports and normal trade traffic. Gaza is GHETTO, ghetto created of Israel. Ghetto completely blockaded, where is allowed only basic human aid, nothing more. Ghetto without watersources (yes, in Warsaw and Lodz were some wells yet), without sevage system, without adequate food, medicine and medical care, ghetto without connections with around world. Situation in Gaza in 2010 year is very similar like situation in Warsaw and Lodz ghetto in 1941 - 1942.
