Hamas is a resistance movement with a so-called self proclaimed government. Excuse me but did you read the charter of Hamas? here one of its fine Hadits "The Day of Judgement will not come about until Muslims fight the Jews (killing the Jews), when the Jew will hide behind stones and trees. The stones and trees will say O Muslims, O Abdulla, there is a Jew behind me, come and kill him. Only the Gharkad tree, would not do that because it is one of the trees of the Jews." (related by al-Bukhari and Muslim). We might assume that things go a little deeper than your article suggests. Let them recognize Israel, an international recognized country, and then we'll see. And do not forget to bring home Gilad Shalit.
