I do not see what is worrying with this poster in the context of terrorism since it talk about kidnapping and not killing. In fact, Israel should be following the Hamas decision to detain people instead of the indiscriminated terrorist attacks against everyone in West Gaza to kill the Hamas "terrorists". Israel and the Western European diaspora justified terrorist attacks against civilians on the claim that terrorists are among the crowd of civilians and terrorist attacks against civilian building on the claim that civilian buildings are terrorist building in disguise, even as they claim that terrorist attacks against civilians are not acceptable regardless of the circumstance. Can Israel use the Hamas approach to detain people like what the police would do? Prior warning to the Palestinians of terrorist attacks is not an excuse for terrorism especially when many Palestinains could not flee in time and those who could flee would loss their daily necessities of life.
