After Israel left Gaza the rockets started falling on Israel. These rockets or the parts needed to build them were smuggled to Israel from Iran and other enemy sources. Israel imposed the blocus to stop the arm smuggling and hence protect its citizens from rockets and other forms of terrorism. If these ships are allowed now to enter Gaza, many other flotillas will follow. Even if this flotilla does not carry any arms, the next ones will certainly try to smuggle them, as Iran will surely try to take advantage of the broken blocus . Hence Israel should not let these "activists" get into Gaza. No matter what!
