I'm sorry, it doesn't matter how many warnings you give them, it is against international law to target civilian infrastructure. This holds true for Israel AND Hamas. Both are guilty of this. Both are wrong!
No, I do not take Hamas at their word. I just quote what they say that is relevant, which is the same for what I do with Israeli comments. In fact, the one about "there are no innocents in Gaza", is a statement from a former IDF soldier who was part of Operation Cast Lead.
I am completely against the occupation. Once that has ended, everything Israel would do after that, would definitely be considered self defense and I would be 100% in support of them. Even the Israeli right. Because everyone in the world, has a right to defend themselves. Including Israel. Including Hamas. But the occupation must end. It is the single cause of all the violence in the that area.
