Two out of three of your sources are rubbish and I think show you up for what you are Theres a lot of claptrap coming from Israel over Hamas being one and the same with ISIS and then you have Sisi simply not liking them because of their connection to the deposed Muslim Brotherhood government in Egypt    Hamas is IslamistNationalist and so the Wahhabis of ISIS see them as heretical and theres not really any evidence to the claims of Hamas and ISIS colluding in the Sinai Its by and large Israeli nonsense of the kind theyve been rattling off since AQ became such a hot issue
